Laser diode rate equations (original) (raw)

The laser diode rate equations model the electrical and optical performance of a laser diode. This system of ordinary differential equations relates the number or density of photons and charge carriers (electrons) in the device to the injection current and to device and material parameters such as carrier lifetime, photon lifetime, and the optical gain. The laser diode rate equations can be formulated with more or less complexity to model different aspects of laser diode behavior with varying accuracy.
