This optical gyroscope uses a unidirectional coupled-resonator waveguide to enhance the Sagnac effect. Thus, this device offers greater sensitivity to rotation than conventional resonant or interferometric fiber-optic gyroscopes.
Light with a narrowband spectrum is launched into the FBG, at a wavelength located on one of the two edges of the reflection peak of the FBG, i.e., at a wavelength where the FBG transmits, rather than reflects, light.

A team from Stanford's Career Development Center has created a software program that comprises a series of online activities and guided reflections for career development.
The Nanophotonic Light-Field (NLF) sensor enables a new generation of light field cameras capable of high sensitivity, high pixel density and faster shutter speeds.
Stanford researchers are using nanowires (NWs) to raise the performance of organic solar cells. Organic solar cells' main weakness is their lack of efficiency compared to in-organic solar cells.
Researchers in Dr. Bingwei Lu's lab have identified genes that could serve as therapeutic targets for the treatment of Parkinson's disease (PD). PD is a common neurodegenerative movement disorder affecting 1% of the population over the age 60.
