2-CM LONG MONOLITHIC MULTISECTION LASER FOR ACTIVE MODELOCKING AT 2.2 GHZ

A 2 cm long three-contact multisection laser has been fabricated for modelocking at very low repetition rates. Active modelocking yields 8.0-12.3 ps pulses at 2.2, 4-3 and 6-5 GHz corresponding to the fundamental, first, and second harmonics of the cavity resonance frequency. This device demonstrates the feasibility of fabricating monolithic pulse sources operating at rates as low as the OC-48 Sonet transmission rate (2-488 Gbit/s).
