Description:

(abstract)

Optically active defects in 2D materials, such as hexagonal boron nitride (hBN) and transition metal dichalcogenides (TMDs), have proven to be an attractive class of single-photon emitters with high brightness, room-temperature op- eration, site-specific engineering of emitter arrays, tunability with external strain and electric fields, and compatibility with a wide variety of host material platforms. In this work, we develop a novel approach to precisely align and embed hBN and TMDs within background-free silicon nitride (SiN) microring resonators. Through the Purcell effect, high- purity hBN emitters exhibit a cavity-enhanced coupling efficiency of 33 ± 12% at room temperature, which exceeds the theoretical limit for cavity-free waveguide-emitter coupling and previous demonstrations by an order-of-magnitude. This work demonstrates the first successful integration of 2D material quantum emitters with microresonators in a foundry-compatible silicon photonics platform, opening a path for scalable quantum photonic chips with on-demand single-photon sources.
