Optics on chip can provide high bandwidth, high speed and ultra-small optoelectronic components. In order to realize this technology one needs to overcome several critical barriers such as coupling to and from the chip, "packing" effective long lengths into micron-sized structures to enable for example optical buffers, and achieving on-chip light emission. High index contrast allows the fabrication of low loss sub-micron size optical elements. In addition, light confining micron-sized structures based on high index contrast can manipulate light and enhance it by orders of magnitude. In this talk I will review the physics and applications of nanophotonics and address the above critical barriers. I will present structures that allow 95% fiber to waveguide coupling in short lengths using high index contrast Si/SiO2 materials. Using Si/SiO2 light confining microcavities, we have demonstrated flat large optical delay over a wide bandwidth. I will also present structures that demonstrate the capability to amplify light emission by factors up to 1000 of Erbium in Si microcavities.
After completing her Ph.D. in 1999 on semiconductor microcavities, Michal Lipson joined the department of Material Science in MIT as a Postdoctoral Associate. Her research in MIT involved the physics and applications of Si-based photonic structures for on-chip applications. Her research demonstrated the first proof that one could achieve strong coupling between light and matter in a Si structure. On July 2001 Lipson joined the school of Electrical and Computer Engineering at Cornell University as an Assistant Professor. She has industrial experience in Photonics, extensive experience in teaching undergraduate and graduate students, as well as publications across a wide range of disciplines related to optoelectronics and nanophotonics.
