Abstract

Single photon emitters within hosts with high refractive indices suffer from low collection efficiencies due to total internal reflection at the host interface. This can be alleviated through shaping the local refractive index environment, specifically through forming open cavities and allowing matching between the emission mode in the host and travelling mode in air. We design micropillars around single photon emitters within aluminium nitride via electromagnetic simulations and show that the collection efficiency can be increased by an order of magnitude compared to the base case. We fabricate the designs through standard clean room procedures and confirm collection enhancement through confocal microscopy.
