Transmitters for OC-768 Networks

Picosecond Laser Sources

These are monolithic integrated mode-locked laser chips mounted on a submount for temperature stabilization.

The laser utilizes a multi-section Semi-Insulating Planar Buried Heterostructure (SIPBH) MQW laser structure on GaInAsP / InP.  The device integrates a gain and absorber section and is configured in an in-line extended cavity configuration.

Features include 1.5 ps pulse widths and repetition rates of 39.813 GHz, 42.657 GHz, or 53.3 GHz.   These can provide an optical clock for OC-768 or OC-768 FEC RZ applications, and optical TDM up to 160 GBit/s including D(Q)PSK modulation.
