High Gain Infrared Collector and Data Node

An infrared collector employs a concentrator formed of a plurality of spatially related gradient-indexed (GRIN) lenses and a photo detector interconnected by optical fibers. Since the GRIN lenses are arranged on a hemispherical shell the concentrator is relatively insensitive to the direction of the incoming infrared radiation. Optical fibers are...

Integrated Optical Polarizer for Silicon-on-Insulator Waveguides

Integrated optics based on silicon-on-insulator platforms are developing extremely fast due to technological compatibility with complementary metal-oxide-semiconductor (CMOS) fabrication process widely accepted in microelectronics. Wayne State researchers have developed a technology which generates an integrated optical polarizer for high index...

Sub-monolayer detection with surface selective vibrational spectroscopy

This invention describes a new system and method for performing surface-selective spectroscopic detection with high sensitivity and low detection limits particularly in the visible and fingerprint mid-infrared spectral regions. The method offers a substantial improvement, 10-fold or more, over existing techniques. This invention has already been reduced...
