Researchers in California plan to announce that they have created a silicon-based chip that can produce laser beams. The New York Times reports Monday that the development will make it possible to use ...

The desktop-sized LPU100 eschews traditional electronics and qubits in favor of lasers, and it can reportedly perform complex AI calculations in nanoseconds. When you purchase through links on our ...

This application note describes a closed loop, computer- controlled, variable attenuator for the control of output power from a tunable laser. It is based on the combination of a 1/2 wave-plate and a ...

The invisible chemicals around and within us can tell many complicated stories. By sensing them, security agents can uncover explosive threats. By monitoring them in our breath, doctors can diagnose ...

Led by Manijeh Razeghi, a team of researchers has designed a new laser technology with high power and high brightness. New advances by Prof. Manijeh Razeghi and her Center for Quantum Devices (CQD) ...

The ring below (from $35; $155 as pictured) was designed, by necessity, on a computer. It began as a 3-D model of a one-inch sphere; then, Silva/Bradshaw–which is Sergio Silva and Matthew ...

Thariq Shanavas is a fourth-year physics PhD student who works in the Gopinath Lab in electrical, computer and energy engineering. He was recently first author on a paper in the journal APL Photonics ...
