High Power CW Lasers

DenseLight’s range of CW lasers offers customers platform agnostic solutions, whether it is the traditional gold box based transceivers or for customers wanting to bond the laser source onto Silicon Photonics platforms to customers who want to mount the lasers on to Laser Micro Packages. Designed and grown at our Wafer Fab in Singapore these proprietary InP based MQW CW lasers come in both Ridge based and BH versions.

Having our own FAB enables to customize these devices – from higher operating temperatures, to customizing it for Silicon Photonics applications (enabling Flip chip and incorporating MFAs for efficient coupling).
