Abstract

Nanohybrid comprising of a nanoresonator and a quantum emitter have shown enhanced optical properties compared to its constituents. Such nanohybrids are highly sensitive to their surrounding medium permittivity, making them suitable for sensing applications which relies on the background permittivity. This feature is a result of the change in resonance conditions in the nanoresonator, which is part of the nanohybrid. Here we investigate how different nanoresonators affect the sensing capabilities of the nanohybrid and use that information to make recommendations on the best nanores-onator for the nanohybrid depending on the application. Our analysis is based on cavity quantum electrodynamics formalism and thus rigorous and accurate. Our results indicate that the graphene resonator based nanohybrids can be used to detect broader permittivity range than MNP based nanohybrids.
