III-Vs Review, 2004 Whatever the viewpoint on the state of play in the telecom/datacom marketplace, it is undeniably the case that the VCSEL is here to stay. Moreover, the potential of this laser diode family is only beginning to be exploited. Much will depend on factors such as materials and device technology, applications and competition in the market from other laser ...
