Optical Communication

SemiNex state-of-the-art DFB lasers provide superior performance, ensuring long life time and high reliability for ensuring data transmission.

 

We use only the highest quality semiconductors with wavelengths at 1310nm and 1550nm.

The narrow linewidth, high side mode suppression ratio (SMSR), and low relative intensity noise (RIN) of our DFB platform can achieve high quality optical communications. The customizable multi-channel DFB array allows Si PIC integration for low cost and miniaturized transceiver design.
