High-power semiconductor lasers represent a cornerstone in modern photonic technology, harnessing advanced semiconductor heterostructures to deliver high-brightness and efficient light sources. These ...

Image showing gold contacts where we bias each laser with DC current. Light is out-coupled from the racetracks using the directional-coupler waveguides along the straight section of either racetrack.

The Finnish company is building its own fabrication facility as demand grows for compact, high-power lasers across quantum, ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240159, discusses on-chip light control of semiconductor optoelectronic devices using integrated metasurfaces. Since the initial ...

Optical injection locking is a technique by which the output of a semiconductor laser is stabilised and synchronised to that of an external “master” laser. This method harnesses the coherent ...

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...
