Optical phase conjugation with gain in a bulk semiconductor

摘要

We experimentally demonstrate a method of high-speed optical amplification using degenerate four-wave mixing in a bulk semiconductor CdTe. In our experiment, both transmitted probe and phase-conjugate beams are amplified in accordance with theory. We propose that this approach, which performs optical splitting with gain, can be used with multiple input signals, leading to potential applications including image amplification, information distribution, and optical computing.
