Silicon nitride photonics for cavity enhancement of single-photon sources

Silicon nitride (SiN) has emerged as an attractive integrated photonic platform due to its broad transparency window and compatibility with heterogeneous integration. This, combined with the ability to engineer nanophotonic cavities that provide strong Purcell enhancement and efficient off-chip collection, makes it well suited for cavity enhancement of next-generation single-photon emitters (SPE) spanning ultraviolet to near-infrared wavelengths. In this talk, I will discuss our recent work on the development of a silicon nitride platform for cavity enhancement of emerging SPEs, with a particular emphasis on two-dimensional materials. This will include a CMOS-compatible fabrication process for heterogeneous integration with hexagonal boron nitride as well as a detailed approach to maximize the optical enhancement of these cavity SPE systems.
