Abstract
According to 2.1, the modulation bandwidth of a laser diode is proportional to the square root of the internal photon density, which is proportional to the output optical power density. For GaAs lasers commonly used in short-distance data communication links, increasing the optical power density can bring about undue degradation or even catastrophic failure of the laser unless the structure of the laser is suitably designed. One common approach to raising the ceiling of reliable operating power of semiconductor lasers is by means of a large optical cavity [29].
