Advanced Laser Diode Simulator

ALDS is a user-friendly and powerful semiconductor laser simulator. ALDS can be applicable to strained-layer muiti-quantum well (SL-MQW) active region; ridge-waveguide (RW) and buried-heterojunction (BH) lateral confinement structures; phase-shift and DFB structures including sampled grating. The program gives device characteristics such as L-I curves, small signal analysis results, large signal performance and noise characteristics including relative intensity noise (RIN) and so on.
