Unidirectional Coherent Phonon Emission in an Optomechanic Nanobeam Containing Coupled Cavities
Nonreciprocal phonon emission is predicted theoretically from the coherent excitation of two coupled optomechanical cavities arranged along a phoxonic crystal nanobeam. The latter consists of a periodic array of holes and stubs and exhibits simultaneous photonic and phononic bandgaps. It is shown th...
