Nonreciprocal optical device based on second-harmonic generation.
We propose a novel device that exhibits nonreciprocity in optical reflection or transmission. The device is formed by two frequency-doubling crystals and a suitable dichroic mirror or a filter. The nonreciprocity may exceed 100 and be accompanied by nonlinear reflection or transmission. Applications in unidirectional and mode-locked lasers are discussed.
