Enhancement Mechanisms for Optical Force in integrated Optics
Wed, May 30, 2007 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering

Dr. Michelle L. PovinelliStanford UniversityAbstract: We investigate the extension of optical micromanipulation to integrated optics. In particular, we consider whether propagating light signals can cause mechanical reconfiguration of a device. While such forces are intrinsically weak, we predict theoretically that significant displacements can be achieved using various enhancement mechanisms. These include the use of high-index materials, high-Q enhancement, and slow light in photonic crystals. Silicon optical waveguides have a considerable refractive index contrast with the surrounding air. We show that the strong confinement of light to silicon magnifies optical forces arising from overlap in the guided modes of neighboring waveguides. Silica microsphere resonators are known to have extremely high cavity quality factors. We show that the quality factor of the resonator magnifies the optical force due to modal overlap between two neighboring spheres. Thirdly, we investigate slow-light enhancement of optical forces using photonic-crystal devices. We show that slow-light velocities give rise to larger forces for the same amount of signal power, enhancing optomechanical coupling effects. In addition to being of fundamental interest, our work suggests that optical manipulation may ultimately provide a route to all-optical conformational control and switching.Biography:Dr. Michelle L. Povinelli is a postdoctoral researcher at Stanford University in the Ginzton Laboratory and the Department of Electrical Engineering. She received a PhD in Physics from MIT in 2004, an M. Phil. in Physics from the University of Cambridge in 1998, and a BA with Honors in Physics from the University of Chicago in 1997. She was awarded several graduate fellowships for her doctoral work, including the Lucent Technologies GRPW Fellowship, the NSF Graduate Fellowship, the MIT Karl Taylor Compton Fellowship, and the Churchill Fellowship. In 2006, she was selected as one of five national recipients of a $20,000 L'Oréal For Women in Science Postdoctoral Fellowship grant. She has co-authored twenty refereed journal articles and holds two US Patents.Date: Wednesday, May 30, 2007

Materials and Manufacturing Directorate, Wright-Patterson Air Force Base
Wed, May 30, 2007 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Dr. James G. GroteUS Air Force Research LaboratoryAbstract: A new class of polymer, based on DNA derived from biowaste materials, has been demonstrated to possess unique optical and electromagnetic properties that no other known polymer has, including tunable conductivity, tunable dielectric constant and ultra low optical and microwave loss. Electronic and electro-optic devices fabricated from this new biopolymer have demonstrated performance that exceeds the performance of the state-of-the-art devices fabricated from current organic-based materials. This new biopolymer may be tomorrow's "silicon" of polymers, with its potential impact on a wide spectrum of both electronic and optoelectronic devices, while at the same time being inexpensive and easy to process. This is significant because it demonstrates that biotechnology is not only applicable for genomic sequencing and clinical diagnosis and treatment, but can also have a major impact on non biotech applications as well, such as electronics and photonics, opening up a whole new field for bioengineering.Biography:Dr. James G. Grote is a Senior Electronics Research Engineer with the Air Force Research Laboratory, Materials and Manufacturing Directorate at Wright-Patterson Air Force Base, Ohio, where he conducts research in polymer based opto-electronics. He is also an adjunct professor at the University of Dayton and University of Cincinnati. Dr. Grote received his BS degree in Electrical Engineering for Ohio University and both his MS and Ph.D. degrees in Electrical Engineering from the University of Dayton, with partial study at the University of California, San Diego. He was a visiting scholar at the Institut d'Optique, Universite de Paris, Sud in the summer of 1995 and a visiting scholar at the University of Southern California, the University of California in Los Angeles and the University of Washington in 2001. Dr. Grote is a Fellow of the International Society for Optical Engineering (SPIE), a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE), and a member of the Optical Society of America (OSA) and the European Optical Society (EOS).Date: Wednesday, May 30, 2007
