Arrangement for damping the resonance in a laser diode
Patent
·
OSTI ID:6461016
An arrangement for damping the resonance in a laser diode includes an additional layer which together with the conventional laser diode form a structure of a bipolar transistor. Therein, the additional layer serves as the collector, the cladding layer next to it as the base, and the active region and the other cladding layer as the emitter. A capacitor is connected across the base and the collector. It is chosen so that at any frequency above a certain selected frequency (f /SUB c/ ) which is far below the resonance frequency (f /SUB res/ ) the capacitor impedance is very low, effectively shorting the base to the collector.
