A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without requiring a new chip for new colors. This form of nonlinear photonics could ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...

How a single silicon chip was designed to be microwave and optical signal-processing engine. The various roles for which this engine can be reconfigured. The performance considerations that were ...

Early-stage disease diagnosis relies on the highly sensitive detection of biomarkers. Optical whispering-gallery-mode (WGM) microcavity sensors have emerged as a highly promising technology for ...
