In a method of amplifying optical input signals over a wide bandwidth, the optical input signals are applied to an optical waveguide made from a rare-earth-doped amorphous material (e.g., erbium-doped yttrium aluminum oxide material).
In certain embodiments, an optical device and a method of use is provided. The optical device can include a fiber Bragg grating and a narrowband optical source. The narrowband optical source can be configured to generate light.
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.
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.
An acoustic sensor and a method of fabricating an acoustic sensor are provided. The acoustic sensor includes at least one photonic crystal structure and an optical fiber having an end optically coupled to the at least one photonic crystal structure.
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.
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.
For the application of human pluripotent stem cell-derived cardiomyocytes in drug discovery, cardiotoxicity testing, disease modeling, and regenerative medicine large numbers of cells need to be derived from a variety of cell lines in a defined, reproducible and cost-efficient
Stanford and Rockefeller researchers have identified and developed dynein-specific inhibitors that have significant medical applications involving mitotic spindle assembly, organelle transport, and primary cilia formation.
Researchers in Dr. Or Gozani's laboratory have produced lysine methyltransferases, histone octomers, purified nucleosomes, and antibodies for use in chromatin and epigenetic research.
