Talk Title: Integrated Photonics in Silicon and Silicon Nitride-on-Silicon Platforms
Abstract: The surging progress in silicon photonics over the past decade has been driven by its potential application in low cost, high bandwidth, wavelength-division multiplexed short reach optical interconnect. Despite significant advances, numerous technical challenges remain, such as the control of resonant devices, the implementation of large swing optical modulators, the management of polarization, the need for improved variation tolerance, an effective means for efficient and broadband fiber-to-chip optical coupling, and approaches to electronic-photonic integration.
In this talk, I will provide an overview of my groupâs progress in addressing these issues in silicon-based photonic platforms. Photonic devices and integrated circuits implemented in standard silicon-on-insulator photonic platforms and a custom silicon nitride-on-silicon platform will be presented. I will describe microring modulators and filters that circumvent conventional limits, the first polarization rotator-splitters and controllers in standard silicon photonic platforms, grating couplers with record-setting bandwidths and insertion losses, and our ongoing efforts in electronic integration. The work paves the path toward very large-scale photonic integrated circuits and terabit-scale optical transceivers.

Talk Title: Foliage Penetration Radar
Abstract: Abstract: Foliage Penetration (FOPEN) Radar is a technical approach to find and characterize man-made objections under dense foliage, as well as characterizing the foliage itself. It has applications in both military surveillance and civilian geospatial imaging. This Tutorial is divided into three parts.
1) The early history of FOPEN Radar: battlefield surveillance and the early experiments in foliage penetration radar are covered. There were some very interesting developments in radar technology that enabled our ability to detect fixed and moving objects under dense foliage. An important breakthrough was the quantification of the radar propagation through foliage, and related scattering and loss effects.
2) FOPEN synthetic aperture radar (SAR) with concentration on development results from several systems. These systems were developed for both military and commercial applications, and during a time of rapid awareness of the need and ability to operate in a dense signal environment. The tutorial quantifies the benefits of polarization diversity in detecting and characterizing both man made and natural objects. Furthermore, there is a clear benefit for use of polarization in false alarm mitigation. Finally the techniques developed for ultra wideband and ultra wide angle image formation will be presented.
3) New research in Multi-mode Ultra-Wideband Radar, with the design of both SAR and moving target indication (MTI) FOPEN systems. Particular note will be taken on the benefits and difficulties in designing these ultra-wideband (UWB) systems, and operation in real world electromagnetic environments. The tutorial will illustrate new technologies that have promise for future multimode operation: the need to detect low minimum discernable velocity; and simultaneous SAR and GMTI operation.

Speaker: Dr. Mark Straayer, Maxim Integrated Products
Talk Title: Data Converters
Abstract: The role that analog-to-digital converters (ADC) play in most electronic systems is growing, and this can be attributed to the two factors. First, it is well known that the reduced power, area, and cost of the digital in advanced process technologies is a motivating factor to integrate more signal processing functions in the digital domain. Second, the ADC performance trajectory of lower power consumption, higher speed, and higher precision resulting from architectural and process advances has been allowing for applications to sample the signal of interest with minimal analog signal processing at the front-end.
This talk will explore a number of topics in this area, highlighting application examples that have seen this trend and diving into technical approaches that make it possible. We will discuss one approach that Maxim has leveraged to achieve state-of-the-art performance with significant power reduction, zero-crossing based converters. In addition, we will explore other technical approaches for ADC designs, including SAR converters, sigma-delta converters, and the VCO-based converters in the context of the expanding role for ADC previously mentioned.

From 2001-2003 he worked at Integrated Sensing Systems, Inc., Ypsilanti, MI, designing custom CMOS IC for capacitive and resonant MEMS sensors in industrial and medical wireless telemetry applications. From 2003-2008 he was a member of the technical staff at MIT Lincoln Laboratory, Lexington, MA, developing mixed-signal circuits for high-speed and RF applications in a variety of process technologies, especially in the area of high-performance and low-power frequency synthesizers.
In 2008 he helped to co-found Cambridge Analog Technologies (CAT), where as Vice President of Product Development he led the technical development of zero-crossing circuits for high performance analog-to-digital converters, taking the technology from MIT research to robust high volume products. In 2011 CAT was acquired by Maxim Integrated Products, and he has continued to lead the design team in establishing circuit architectures and roadmaps, effective project management, and recruiting technical talent.

Talk Title: Terahertz and Millimeter-Wave Frequency Generation and Synthesis in Silicon
Abstract: Terahertz (THz) and millimeter-wave (mm-wave) imaging and sensing is considered to be one of the emerging and disruptive technologies over the next decade. THz (including the W-band) waves pass through non-conducting materials such as clothes, paper, wood and brick and so cameras sensitive to them can peer inside envelopes, into living rooms and "frisk" people at distance. THz/mm-wave imaging/sensing systems, therefore, will be key enabling components in applications such as security surveillance (to find concealed weapons and explosives), non-destructive testing, biology, radio astronomy, multi-gigabit wireless connectivity, and medical imaging. One of the most critical and daunting tasks in a THz/mm-wave system is signal generation and frequency synthesis. This lecture presents a comprehensive overview and comparative study of research efforts which have explored several circuit techniques and architectures leading to highly efficient frequency synthesis and signal generation in silicon at mm-wave and terahertz frequencies.
Biography: Payam Heydari received his B.S. and M.S. degrees (Honors) in Electrical Engineering from Sharif University of Technology in 1992 and 1995, respectively. He received his Ph.D. degree from the University of Southern California in 2001. He is currently a Professor of Electrical Engineering at the University of California, Irvine. He has received many awards and recognitions and published more than 110 journal and conference papers

Talk Title: Timing Over Wireless
Abstract: Traditionally wireless technology has been used to communicate messages. However, in this talk will focus on two other applications, namely, precise positioning in indoor environments, and clock parameter exchange of electronic nodes over wireless. Both these applications rely on measuring and estimating time related parameters over wireless.
Our work on indoor positioning is based on a new method of distributed positioning which exploits time delays in transmission scheduling. This method achieves distributed positioning, where every node in a network knows the position of every other node, without requiring any communication among nodes. The underlying idea can also be extended to self localize a passive network node. Via extensive experiments we verify that our method is a very efficient cooperative distributed position methodology that in surpasses the capabilities and performance of many alternative in the literature.
Precise wireless clock synchronization is the holy grail of achieving efficiency and coordination in wireless sensor networks. I will describe a new technique which provides range and clock parameter estimation simultaneously between any two node over wireless. In order to experimentally verify the algorithm, we developed a new in-house measurement model.
Accuracies obtained by our above models are in the order of sub-Hertz for clock frequency error estimation, and sub-nanosecond for clock phase error estimation, and less than 30 cm for range estimation over a range up to 10 meters.
Precisely estimating timing parameters over wireless results in hardware constraints. Continuous improvement in the hardware which can accomplish the tasks of positioning, clock synchronization and communication will be discussed, and our efforts towards developing an ultra-wideband (UWB) testbed will be explained.
