High-power high-efficiency 2d vcsel arrays
WebMar 14, 2011 · way is to integrate elements into two-dimensional (2D) arrays on a single chip. High array density and appropriate heat spreading make it easier to obtain a high output power. Up to now, effort has been given to studies of increasing the output power of VCSEL. For single devices, a maximum output power of 1.95W for continuous-wave (CW) … WebIn this paper we present several new results on 808nm VCSELs and high-power 808nm 2D VCSEL arrays. First, we present high-efficiency and high single-mode power results for top-emitting single devices. Second, we describe the processing and packaging steps involved in fabricating large 2D 808nm VCSEL arrays.
