Typically, for lasers in optical communication systems, waveguide designs are used to achieve a single transverse mode. By adjusting the thickness of the surrounding area of the cladding layer and the etching depth of the ridge in the ridge waveguide device, a single mode device can be obtained. The importance of lasers is reflected in the following aspects:A chip without ridge waveguide design an...
According to a recent report by Congic Business Intelligence, the global medical laser fiber market is expected to grow significantly at a compound annual growth rate of 6.9% from 2023 to 2030. This growth is attributed to the increasing popularity of minimally invasive surgery worldwide.The medical laser fiber market is expected to expand strongly, reaching $1.369 billion by 2030.

A new laser generation method: a laser without a reflector. This study, conducted by a team of physicists from the University of Innsbruck and Harvard University, shows that quantum emitters with spacing smaller than the wavelength can achieve constructive synchronization of photon emission, resulting in bright and extremely narrow bandwidth beams, even without any optical resonant cavities.The ac...
