Speaker: Nader Engheta, University of Pennsylvania
Talk Title: Metaphotonics: Form vs Function
Abstract: As the fields of metamaterials and nanophotonics reach certain levels of development, new directions and novel vistas appear on the horizon. Modularization, parameterization and functionalization of metamaterials and nanoscale photonics may provide new optical characteristics and functionalities for the platforms of metaphotonics. Indeed, metamaterial “forms” lead to “functions”. These include (a) the extreme-parameter nanophotonics, (b) materials that may function as optical nanocircuits (“optical metatronics” -- a platform for nanoscale information processing), (c) graphene metamaterials as one-atom-thick optical devices, (d) nanomaterials that perform mathematical operations (nanoscale analog computers), (e) nonreciprocal nanostructures for unusual flow of photons, and (f) metamaterial “bits” and “bytes” as building blocks for digital metamaterials, to name a few. In my group we are investigating a variety of features and properties of these concepts and directions in functionalizing metamaterials, and are exploring new classes of phenomena and potential applications. I will discuss some of these topics, present our latest results, and forecast future directions and possibilities.

Speaker: Donald Lie, Texas Tech University
Talk Title: Design of Silicon-Based Envelope-Tracking Power Amplifiers (ET-PA) for Highly-Efficient Broadband Wireless Applications; also a Briefing on Medical Electronics Research in My Group
Abstract: The latest broadband wireless (4G/WLAN) standards utilize inherent spectral-efficient modulation schemes with high peak-to-average power ratios (PAPR) and wide signal bandwidth, which demand high linearity RF power amplifier (PA) design techniques that can offer excellent power-added efficiency (PAE) at both the maximum peak power and the power back-off levels to provide power saving. As suggested by the recent market trends and the literature, the dynamic power-supply modulation techniques (e.g., the envelope-elimination-and-restoration (EER) and the envelope-tracking (ET) schemes) are among the most effective methods for RF PA efficiency enhancement at both peak and back-off output power modes for various DoD and commercial applications. I would, therefore, present some of the latest design techniques, research, and market trends of high efficiency supply-modulated RF PAs, with emphasis on the silicon-based ET-PA design done in my group. I will also provide a brief highlight on some of the medical electronics research in my group.

Speaker: Austin J. Minnich, California Institute of Technology
Talk Title: Heat Under the Microscope: Uncovering the microscopic processes that govern thermal transport
Abstract: Thermal transport is a ubiquitous process that plays an essential role in nearly every technological application, ranging from space power generation to consumer electronics. In many of these applications, heat is carried by phonons, or quanta of lattice vibrations. Compared to other energy carriers such as electrons or photons, the microscopic properties of thermal phonons remain remarkably poorly understood, with much of our understanding still based on semi-empirical studies from over fifty years ago. In this talk, I will describe our efforts to uncover the microscopic processes that govern thermal transport by phonons using both experiment and computation. In particular, I will describe a new experimental technique that has enabled the first direct measurements of phonon mean free paths in a wide range of crystalline solids. I will demonstrate how these insights are advancing applications ranging from thermoelectric waste heat recovery to radio astronomy.

Thu, Jan 30, 2014 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Professor Elahe Nezami, Keck School of Medicine of USC
Talk Title: Connecting the Campus: Establishing New Pathways for Interdisciplinary Innovation, Collaboration, and Programming
Abstract: The continued globalization of the world and complementary globalization of health-related services and industries demands that education likewise transform to adequately prepare students to become leaders in the fields of public health and medicine. New programs must train students in multiple disciplines to ground their healthcare knowledge in cultural, social, political, and technical expertise. Students desire and demand a broader set of skills from their training, and universities must anticipate the advances in the fields into which their graduates will enter to provide such training. Collaborating and partnering with colleagues across campus allows for the development and creation of cutting-edge education and training programs that are designed to prepare students to become future leaders of industry, even as industries merge and change and expectations of graduates’ expertise broaden. Additionally, the creation of new collaborative programs allows for the expansion of adaptive learning environments and the integration of the newest technologies and pedagogical approaches. By developing partnerships across the schools of the university, innovative new programs will graduate new innovators, and USC will remain at the fore of educational excellence. The creation of interdisciplinary programs at USC at the undergraduate and graduate level has yielded outstanding results thus far, encouraging new partnerships in new fields with high growth potential. The programs, and potential programs will be outlined and highlighted.
Biography: Dr. Elahe Nezami serves as director of the Health Promotion and Disease Prevention Studies and Global Health programs at the undergraduate level, and the Master of Science in Global Medicine program at the graduate level. She is also the associate dean for Undergraduate, Masters, and Professional programs of the Keck School of Medicine of USC and co-director of the Wireless Health Technology program.
Dr. Nezami’s research examines determinants of behavioral risk factors for chronic diseases, cancer, and cardiovascular diseases. Other research projects include examination of personality characteristics in relation to cardiovascular disease, and self-medication theories of smoking. Dr. Nezami received her M.A. in Clinical Psychology from the University of Houston and her Ph.D. in Clinical Psychology from the University of Southern California, where she also completed a post-doctoral fellowship.

How Small Can One Shrink A Laser?
Fri, Jan 31, 2014 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Jacob B. Khurgin, Johns Hopkins University
Talk Title: How Small Can One Shrink A Laser?
Abstract: Recently there has been a surge in activity devoted to development of the nano-scale lasers, in particularly the lasers employing surface-plasmon polaritons in metal dielectric structures (“spasers”). In my talk I will review the recent effort and present a theory that would clearly outline the fundamental limits of how small can the nano-laser actually be. First I will show that in order to go beyond diffraction limit one absolutely must use metallic structures with associated loss. Then I will show that the lasing threshold of the single mode metal-semiconductor nano-laser (spaser) is determined only by the photon absorption rate in the metal and exhibits very weak dependence on the composition, shape, size (as long as it is less than half-wavelength) and temperature of the gain medium. This threshold current is on the order of a few tens of micro-amperes for most semiconductor-metal combinations which leads to unattainably high threshold current densities for a substantially subwavelength laser (spaser). I will also discuss the coherence properties of nano-laser, and the modulation speed, which is comparable to that of a standard VCSEL. Therefore, in my view, surface plasmon emitting diodes, (SPED’s), operating far below “spasing” threshold may be a more viable option for the chip scale integrated nanophotonics.
Biography: Jacob B. Khurgin had graduated with MS in Optics from the Institute of Fine Mechanics and Optics in St Petersburg, Russia (now called something else) in the previous millennium (1979), and shortly thereafter, in 1980 he had emigrated to US, where, to his own greatest surprise, he almost immediately landed what at a time seemed to be a meaningful job with Philips Laboratories of NV Philips in Briarcliff Manor, NY. There for 8 years he worked with various degrees of success on miniature solid-state lasers, II-VI semiconductor lasers, various display and lighting fixtures, X-ray imaging, and, more important, on small appliances such as electric shavers and coffeemakers (for which he holds 3 patents). Simultaneously he was pursuing his graduate studies at Polytechnic Institute of NY (nowadays elevated to NYU School of Engineering) where he had received PhD in Electrical Engineering in Jan. 1987. In Jan. 1988, prompted by a promotion to a Department Manager, Khurgin’s industrial career came to an abrupt end, and he had joined the ECE department of Johns Hopkins University, where, despite his ever present reservations about that place, he had settled down and is currently a Professor. His research topics over the years included an eclectic mixture of optics of semiconductor nanostructures, nonlinear optical devices, lasers, optical communications, THz radiation, microwave photonics, cavity optomechanics, slow light propagation, and rudimentary condensed matter physics. Currently he is working in the areas of mid-infrared lasers and detectors, phonon engineering for high frequency transistors, disorder in condensed matter physics, plasmonics (or lack of such), coherent secure optical communications, and silicon photonics. His publications include 6 book chapters, one book edited, 240 papers in refereed journals and 28 patents. Prof Khurgin had held a position of a Visiting Professor in an array of institutions of variable degrees of repute â Princeton, UCLA, Brown, Ecole Normale Superieure (Paris), Ecole Polytechnique (Paris) , EPFL (Lausanne), and so on. Prof. Khurgin is a Fellow of American Physical Society and Optical Society of America.

Talk Title: Low loss millimeter-wave switches based on the Vanadium Dioxide Metal - Insulator - Transition
Abstract: A new ultra-low-loss and broad band millimeter wave switch technology based on the reversible metal/insulator phase transition of vanadium dioxide has been developed. We report having fabricated series configured, single-pole single-throw (SPST) switches having measured S-parameters from DC to 110 GHz. The on-state insertion loss is 0.2 dB and off-state isolation is 21 dB at 50 GHz. The resulting impedance contrast ratio, ZOFF / ZON, is greater than 500:1 at 50 GHz (i.e. cut-off frequency fc ~ 40 THz). As a demonstration of the technology's utility, we also present the results of a 2-bit real time delay phase shifter incorporating a pair of VO2 SP4T switches. This switch technology's high impedance contrast ratio combined with its compactness, ease of integration, and low voltage operation make it an enabler of previously unachievable high-performance millimeter wave FPGAs.
Biography: Mark Field was awarded a bachelors degree in physics and theoretical physics from the University of Cambridge, United Kingdom, in 1986, and a masters degree in microelectronics and computer engineering from the University of Surrey, United Kingdom. In 1988 he returned to Cambridge University to study for a Ph.D., performing research into single electron devices in the semiconductor physics group at the Cavendish laboratory under Professor Michael Pepper. Dr. Field earned the Ph.D. in experimental physics in December 1991 and was awarded a research fellowship at Trinity Hall Cambridge.
In 1996 he moved to the University of California at Santa Barbara, and worked as a postdoctoral researcher with Professor David Awschalom on magnetic force microscopy of nanoscale magnets. Dr. Field subsequently joined Symyx Technologies, a startup company in Santa Clara California, where he worked on combinatorial materials science, using high throughput synthesis and measurement to discover new magnetic materials. In October 2000 Dr. Field joined Teledyne Scientific (formerly Rockwell) in Thousand Oaks California as a senior scientist. His currently interests include nanoscale electronics and phase change materials.
