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.
