This code simulates a semiconductor laser diode subject to optical self-feedback. The diode's optical intensity and the free electron carrier population are calculated over time.
Parameters are hard-coded into the "SemiconductorSimulationDDE_MM.m" file, and include:
- diode coefficients taken from a simulation of near infrared diodes (Ryan et al 1994)
- simulation parameters such as number of modes to simulate, time of simulation, laser bias current, optical feedback strength, optical feedback delay, etc
- current modulation parameters including modulation depth and modulation frequency
