Abstract

Circuit model for the quantum well (QW) laser diode has been developed from the rate equations . The model L simulated using the circuit simulation program SPICE2 and validated by comparing dc and transient analysis with PubIShed data. Further, the model in conjunctionwith the optical fiber and photodetectormodel constitutingan optical link has been simulated. Circuit models for gain switched OW lasers are developed and picosecond pulses of 7 and 2 pSCC F\VHM corresponding to the second and third quantised state transitions, respectively were observed by simulating the models. A remarkable reduclion in the output pulsewidth that is observed for the third quantised level transitions demonstrates the significance of higher subband transitions for the generation of ultra short pulses. Effects of cavity U:nth and number of wells on the output puLse shape were also analyzed.
