High power VCSEL array for 3D Sensing and Imaging

Constance Chang-Hasnain

Prof. Chang-Hasnain's group published the first 940nm high power VCSEL array emitting 5W optical power. This work was published in Electronics Letters in 1998. Recently this wavelength band of VCSEL array has been adopted for the next generation of 3D sensing in smart phones and other devices with projected billion units per year in the next a few years. Prof. Chang-Hasnain's group is currently working on high power devices for longer distance sensing.
