Proposal for an optomechanical traveling wave phonon–photon translator

Abstract

In this article we describe a general optomechanical system for converting\nphotons to phonons in an efficient, and reversible manner. We analyze\nclassically and quantum mechanically the conversion process and proceed to a\nmore concrete description of a phonon-photon translator formed from coupled\nphotonic and phononic crystal planar circuits. Applications of the\nphonon-photon translator to RF-microwave photonics and circuit QED, including\nproposals utilizing this system for optical wavelength conversion, long-lived\nquantum memory and state transfer from optical to superconducting qubits are\nconsidered.\n
