Abstract
A four-wave mixer which uses a multiple quantum well structure as a nonlinear optical material is provided. There are provided means for providing a first beam of light which propagates through said multiple quantum well structure, and means for providing a second beam of light which also propagates through said multiple quantum well structure and substantially overlaps said first beam of light within said MQW structure. At least one ouput phase conjugate beam of light is produced by interaction of said first and said second beams of light with said multiple quantum well structure. An alternate embodiment has two counterpropagating pump beams and a probe beam of light which produce a backward scattered phase conjugate beam of light.
