Abstract
A mode matching gain element for an optical system is described, that supports a single mode of the optical signal, and that matches the incoming wavefront to a required outgoing wavefront. The incoming wavefront is passed through a phase conjugating structure, and the mode of the gain element is matched to the mode of the input and output optic fibers. The phase conjugating structure includes lenses or mirrors which time-reverse the incoming signal.
