Product Description

Semiconductor laser chips are lasers that use semiconductor materials as gain media and emit light through transitions between semiconductor energy bands. This type of chip usually uses a natural cleavage surface as a resonant cavity and has the advantages of wide wavelength coverage, small size, stable structure, diverse pumping methods, high yield, good reliability, and easy high-speed modulation.

 

As a key component, laser chips have market potential and can be widely used in telecommunications and data center infrastructure, consumer electronics, automotive electronics, industrial manufacturing, satellite communications, photonic computing, VR, and other fields.
