    with Silicon Nitride Microresonators
  title_type: original
  lang: en

## Description

- description: 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.
