# Single Photon Generation in a Cavity Optomechanical System induced by a Nonlinear Photonic Crystal

## TL;DR

This paper introduces a new method for achieving single-photon blockade in a weakly driven cavity optomechanical system using a nonlinear photonic crystal, enabling photon control at telecommunication wavelengths without requiring strong coupling.

## Contribution

The scheme relaxes the need for strong optomechanical coupling, allowing photon blockade in weaker coupling regimes within hybrid systems.

## Key findings

- Sub-Poissonian photon statistics achieved at weak coupling
- Photon blockade possible at telecommunication wavelengths
- Relaxed coupling strength requirements for photon blockade

## Abstract

We propose a novel scheme for realizing single-photon blockade in a weakly driven hybrid cavity optomechanical system consisting of a nonlinear photonic crystal. Sub-Poissonian statistics is realized even when the single-photon optomechanical coupling strength is smaller than the decay rate of the optical mode. The scheme relaxes the requirement of strong coupling for photon blockade in optomechanical systems. It is shown that photon blockade could be generated at the telecommunication wavelength.
