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 rate equations may be solved by numerical integration to obtain a time-domain solution, or used to
Laser diodes are semiconductor lasers with a current-carrying p–n junction as the gain medium. They are the most important type of electrically pumped lasers.
Laser diodes are highly susceptible to damage from forward and reverse voltage surges and transients, and they require a special set of
When laser diode is driven in excess of the maximum ratings, it causes not only instant breakdown or deterioration but also considerable reduction in reliability.
Laser diodes consist of a p-n diode with an active region where electrons and holes recombine resulting in light emission. In addition, a laser diode contains an optical cavity where stimulated emission takes
Laser diodes are unique compared with other types of lasers. A little background knowledge of laser diodes will be helpful for the readers to understand the contents of this book. We will only briefly
