Demonstration of hexagonal boron nitride optical microcavities with Q > 200,000

Abstract

Hexagonal boron nitride is a unique opto-electrical 2D material that hosts ultra-bright quantum emitters and is an emerging candidate for integrated quantum-optical system. Here we demonstrate hBN integrated microdisk optical resonators with optical quality factor > 2.8 x 10(5). (C) 2020 The Author(s)
