Coherent Population Trapping
Phase sensitive amplification enabled by coherent population trapping
... Abstract We isolate a novel four-wave mixing process, enabled by coherent population trapping (CPT), leading to efficient phase sensitive amplification. This process is permitted by the exploitation of ...
