Signal 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.

Digital coherent communication applications

MicroITLA

Wavelength tunable LD with drive circuit based on industry standard OIF.

米兰ac体育

Nano-ITLA

This LD is even smaller and lower power consumption than MicorITLA.
