Abstract
A fully quantum-mechanical travelling-wave time-domain model for a Fabry—Perot laser diode is presented. Extending the powerful transmission-line techniques proposed by Lowery, the model treats both the optical field and carrier populations quantum-mechanically. The Glauber function is used to represent the field, and correct correlated carrier and field-noise sources model fluctuations. It is believed to be the first presentation of a realistic quantum model for a laser diode which includes spatial hole burning, multi-moded behaviour and photon fluctuations on a picosecond timescale, together with a quantum-mechanically correct treatment of line width and intensity fluctuations.
