On-chip laser diodes based on quantum well (QW) and quantum dot (QD) semiconductor materials have become the primary technology for several applications due to their excellent characteristics, ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

"One current method to narrow laser linewidth uses devices called Brillouin lasers, which use sound waves to interact with light, but the effect is relatively weak—typically narrowing by only tens to ...

A new publication from Opto-Electronic Advances, DOI 10.29026/oea.2023.210149, discusses ultra-high spectral purity laser derived from weak external distributed perturbation. Laser has the ...

For experiments that require ultra-precise measurements and control over atoms -- think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates -- lasers are the technology of ...

SUGAR LAND, Texas - Applied Optoelectronics Inc. (NASDAQ:AAOI) announced today the development of a new 400-milliwatt narrow-linewidth pump laser designed for silicon photonics and co-packaged optics ...
