Abstract

Phoxonic crystals can exhibit dual phononic/photonic band gaps. Therefore, the confinement of both acoustic and optical waves in a phoxonic cavity can allow the enhancement of their interaction. In this paper, we discuss our recent theoretical works on the strength of the optomechanic coupling, based on both photoelastic and moving interfaces mechanisms, in nanobeam phoxonic crystals cavities.

Highlights

There has been a great deal of recent interest about optomechanical interaction in different structures based on slabs[1,2,3] and nanobeams[4,5] using well-defined cavities
We study optomechanic interactions in phoxonic crystals which are defined as dual phononic/photonic crystals that can exhibit simultaneously phononic and photonic band gaps
We have studied theoretically this optomechanic interaction in different (2D6,7, slabs[8], and strip11,12) phoxonic crystals cavities

Summary

Introduction

There has been a great deal of recent interest about optomechanical interaction in different structures based on slabs[1,2,3] and nanobeams[4,5] using well-defined cavities. Most of these works considered localized phonons and photons that are not necessarily trapped inside a photonic and/or a phononic band gap. We study optomechanic interactions in phoxonic crystals which are defined as dual phononic/photonic crystals that can exhibit simultaneously phononic and photonic band gaps. This paper will focus on the results of the strip waveguide structures
