Two dimensional optomechanical crystal designs for microwave-optical transduction

ORAL

Abstract

Conversion between microwave and optical frequencies via transduction with optomechanical devices is a topic of significant current interest, particularly for applications in quantum communication [1-3]. This process requires cooling the microwave-frequency mechanical resonator to the ground state, typically at mK temperatures. One dimensional optomechanical crystals have been operated in the quantum limit [4], but are limited by laser heating. Two dimensional structures may afford better thermal performance with only a minor reduction in optomechanical coupling strength. In this talk I will discuss ongoing efforts towards a two dimensional optomechanical crystal and cavity design, whilst using piezoelectric materials to convert microwave electrical signals to mechanical motion.
