- *Abstract
-
Researchers at the University of California, Berkeley, have developed a method of fabricating 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. One method of fabrication uses a temperature dependent growth rate to create the devices. Alternatively, uniform growth is performed followed by a temperature dependent desorption technique. These techniques provided desired wavelength span and desired characteristics.
