Pump light sources

We have a lineup of InP-based semiconductor lasers that we have developed over many years, mainly for use in intensity modulation/direct detection (IMDD) communications, where the transmission distance is short, and for digital coherent communications, where signals are transmitted over long distances using the phase and polarization of light.
