Paper Abstract

A record room temperature small-signal modulation bandwidth of 17 GHz is reported for vapor phase regrown 1.3 μm InGaAsP buried heterostructure (BH) lasers operated at a pulse bias optical power of only 12 mW/facet. Under cw bias conditions a band-width of 12 GHz is achieved. The optical modulation amplitude remains flat in sharp contrast to other types of BH lasers which exhibit strong signal roll-off at frequencies well below the resonance frequency. The modulation bandwidth is attained by increasing the p-doping level in the active region and by the choice of short cavity length. The device is grown on a conductive substrate indicating that it is unnecessary to use a semi-insulating substrate to obtain flat optical response in these vapor phase regrown BH lasers.
