Abstract
AbstractDiamond is a material of choice in the pursuit of integrated quantum photonic technologies. So far, the majority of photonic devices fabricated from diamond are made from (100)‐oriented crystals. In this work, we demonstrate a methodology for the fabrication of optically active membranes from (111)‐oriented diamond. We use a liftoff technique to generate membranes, followed by chemical vapor deposition of diamond in the presence of silicon to generate homogenous silicon vacancy color centers with emission properties that are superior to those in (100)‐oriented diamond. We further use the diamond membranes to fabricate microring resonators with quality factors exceeding ~ 3000. Supported by finite‐difference time‐domain calculations, we discuss the advantages of (111)‐oriented structures as building blocks for quantum nanophotonic devices.image
Highlights
It enables enhancement of the photon emission flux from the single color centers (for instance by using diamond pillars[16])
Our work launches a new approach for the fabrication of diamond devices with different crystallographic orientations
Given the similar thicknesses of the membranes after the thinning step, the difference in PL intensity is attributed to a better incorporation of the SiV into the growing (111)oriented diamond membrane
Summary
It enables enhancement of the photon emission flux from the single color centers (for instance by using diamond pillars[16]). Our work launches a new approach for the fabrication of diamond devices with different crystallographic orientations.
