Abstract
The present invention provides multiple-wavelength vertical-cavity surface-emitting laser (“MW-VCSEL”) arrays. These arrays are fabricated in a molecular beam epitaxy system or the like using two patterned-substrate growth techniques. The growth techniques can be used with an in-situ laser reflectometry. In one embodiment, a temperature dependent growth rate to create the devices is provided. In an alternative aspect, uniform growth is performed followed by a temperature-dependent desorption technique. These techniques provided desired wavelength span and desired characteristics.
