An optical hydrophone that is insensitive to hydrostatic pressure, yet capable of measuring acoustic pressures as low as the background noise in the ocean in a broad frequency range of 1 Hz to 100 kHz is reported.
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.
