Cat's Eye Multiple Quantum Well Modulating Retro-reflector

摘要

A new kind of modulating retro-reflector using cat's eye optics and a multiple quantum well electro-absorption modulator array is described. The device exhibits retroreflection over a 30 degree field of view and can support data rates of up to 50 Mbps using 1 mm pixels. The use of the device in free space optical communication is discussed.
