Abstract
A vertical-cavity surface-emitting laser comprises one or more quantum well layers and one or more barrier layers to define an gain region, a first mirror means and a second mirror means, wherein the first and second mirror means define a resonator. Moreover, the vertical-cavity surface-emitting laser further comprises a first indium phosphide layer adjacent to the gain region and a second indium phosphide layer adjacent to the gain region to define a laser cavity.
