Conventional semiconductor photodiode materials (silicon, indium gallium arsenide, mercury cadmium telluride, and so on), while extremely useful in photonics, have sensitivities that span only small portions of the visible/infrared (IR) spectrum.

Bench-top diamond Brillouin laser needs no waveguides for light/sound interaction, has more than 10 W output power.

The program includes Lumotive’s M20 solid-state lidar evaluation kit, product customization, and technical support: Application deadline is March 31, 2021.

Created at Harvard SEAS, the metasurface lens has a large bandwidth of 460 to 700 nm and a numerical aperture of 0.2.

An iron-based metal-organic semiconductor in thin-film form detects visible through near-IR radiation.

Silicon photonic chips will be made possible by light-emitting hexagonal silicon-germanium alloys formed into nanowires.

Lidar as a main sensor for autonomous vehicles (AVs) is still too expensive; cameras could work, but are there any other potential optical sensing technologies for AVs?

Block MEMS eye-safe lasers will be used to to generate chemical detection maps via standoff sensing in a complex 3D urban topography.

F-theta lenses have a laser spot position linearly proportional to the scan angle and are thus useful in many laser-scanning applications.

In an MIT Lincoln Labs project, potentially blinding laser beams are triangulated by their scattered light and pinpointed using Google Earth.

Multifunctional planar lens images well, also separates left- from right-circularly polarized light.
