SemiNex DFB laser diodes cater to a wide array of applications, including:-
AI Data Centres
AI Data CentresHigh-power CW O-band DFB laser diodes deliver the narrow linewidth and optical stability required for next-generation AI data centre interconnects. By enabling co-packaged optics (CPO) and external laser small form factor pluggable (ELSFP) architectures, SemiNex DFB lasers provide reliable light sources that enable scalable silicon photonics platforms and optical networks that are both scalable and high-density.
Optical Networks
Optical NetworksSemiNex state-of-the-art DFB lasers at 1310nm and 1550nm provide superior performance, ensuring long life time and high reliability for ensuring data transmission. By offering a combination of narrow linewidth, excellent side mode suppression ratio (SMSR), and low relative intensity noise (RIN) SemiNex DFBs extend transmission reach in networks.
In both applications, customisable options for DFB arrays, including multichannel and multi-wavelength configurations are available to meet the specific requirements of advanced solutions such as Si PIC integration for low cost and miniaturised transceiver design.
