Diamond as a material for monolithically integrated optical and optomechanical devices

摘要

Diamond provides superior optical and mechanical material properties, makingit a prime candidate for the realization of integrated optomechanical circuits.Because diamond sub- strates have matured in size, efficient nanostructuringmethods can be used to realize full-scale integrated devices. Here we reviewoptical and mechanical resonators fab- ricated from polycrystalline as well assingle crystalline diamond. We present relevant material properties withrespect to implementing optomechanical devices and compare them with othermaterial systems. We give an overview of diamond integrated optomechanicalcircuits and present the optical readout mechanism and the actuation viaoptical or electrostatic forces that have been implemented to date. Bycombining diamond nanophotonic circuits with superconducting nanowires singlephotons can be efficiently detected on such chips and we outline how futuresingle photon optomechanical circuits can be realized on this platform.
