Photon-induced tunneling in optomechanical systems

TL;DR

This paper explores photon-induced tunneling in optomechanical systems, demonstrating how multiple photons can enter the cavity simultaneously, offering an alternative method for photon control beyond photon blockade.

Contribution

It introduces the concept of photon-induced tunneling in optomechanical systems and provides analytical and numerical evidence for multi-photon tunneling phenomena.

Findings

Two- and three-photon tunneling can occur by avoiding single-photon blockade.

Analytical and numerical methods confirm the possibility of photon tunneling.

Provides a new approach for photon control using a mechanical resonator.

Abstract

In contrast to recent studies [Rabl, Phys. Rev. Lett. 107, 063601 (2011); Nunnenkamp et al., Phys. Rev. Lett. 107, 063602 (2011)] on photon blockade that prevents subsequent photons from resonantly entering the cavity in optomechanical systems, we study the photon-induced tunneling that increases the probability of admitting subsequent photons in those systems. In particular, we analytically and numerically show how twoor three-photon tunneling can occur by avoiding single-photon blockade. Our study provides another way on photon control using a single mechanical resonator in optomechanical systems.
