Monolithic integration of solid-state color centers with photonic elements ofthe same material is a promising approach to overcome the constraints offabrication complexity and coupling losses in traditional hybrid integrationapproaches. A wide band-gap, low-loss silicon nitride (SiN) platform is amature technology, having CMOS compatibility, widely used in hybrid integratedphotonics and optoelectronics. However, it has been shown that certain growthconditions enable the SiN material to host color centers, whose origin iscurrently under investigation. In this work, we have engineered a noveltechnique for the efficient coupling of these intrinsic emitters into thewhispering gallery modes (WGMs) of the SiN microring cavity -- which has notbeen explored previously. We have engineered a subwavelength-sized notch intothe rim of the SiN microring structure, to optimize the collection efficiencyof the cavity-coupled enhanced photoluminescence (PL) spectra at roomtemperature. The platform presented in this work will enable the development ofmonolithic integration of color centers with nanophotonic elements forapplication to quantum photonic technologies.
