Bipolar cascade arrow laser

摘要

A bipolar cascade-ARROW laser includes a plurality of core regions, at least one spacer disposed between each the plurality of core regions with each of the at least one spacers provided from a material having an index of refraction which is higher than an index of refraction of a material from which the core regions are provided. The bipolar cascade-ARROW laser further includes an anti-reflector disposed against each of the outermost ones of the core regions and at least one quantum well disposed in each of the plurality of core regions.
