SUMMARY:ECE 600 Seminar: Silicon Nanomembrane based Photonic Crystal N
 anostructures for On-chip Open Sensor Systems\, Prof. Ray Chen\, Unive
 rsity of Texas-Austin
DESCRIPTION:We experimentally demonstrate a myriad of devices on the s
 ilicon nanmomembrane based photonic crystal platforms for chip-integra
 ted optical absorption spectroscopy and chip-integrated biomolecular m
 icroarray assays. Infrared optical absorption spectroscopy and biomole
 cular assays based on conjugate-specific binding principles represent 
 two dominant sensing mechanisms for a wide spectrum of applications in
  environmental pollution sensing in air and water\, chem-bio agents an
 d explosives detection for national security\, microbial contamination
  sensing in food and beverages to name a few. The easy scalability of 
 photonic crystal devices to any wavelength ensures that the sensing pr
 inciples hold across a wide electromagnetic spectrum. Silicon\, the wo
 rk horse of the electronics industry\, is an ideal platform for the ab
 ove optical sensing applications.
