A laser diode model based on temperature dependent rate equations

Terms are included in the model to account for the variation in the laser´s differential gain coefficient and transparency carrier density with temperature. The model shows good agreement with DC experimental results and is useful for the design of the control circuitry of laser diode-based optical transmitters operating over a wide range of temperatures. This is particularly important when noncooled lasers are used. The model can easily be extended to investigate transient behavior of the laser with change in temperature.<>
