Narrow Main Beam, Low Side Lobes! High-Performance Electro-Optic Beam Steering with Thin-Film Lithium Niobate Optical ...

A nanoscale optical device has been developed that allows independent control over the intensity and phase of light. By applying voltage, this innovative device can freely manipulate the phase and ...

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At ...

Historically, metasurface research has concentrated on the full manipulation of light's characteristics, resulting in a diverse array of optical devices such as metalenses, metaholograms, and beam ...

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending spacetime, creating a point of no return. While black holes have fascinated ...

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

A new "lensless" device could help, as it uses light to instantly detect harmful microorganisms. Usually, in order to check drinking water for bacteria, a sample of that water must be cultured in a ...

Kerry Vahala and collaborators from UC Santa Barbara have found a unique solution to an optics problem. When we last checked in with Caltech's Kerry Vahala three years ago, his lab had recently ...
