Abstract
We present the basic ingredients of continuum optomechanics, i.e. the suitable extension of cavity-optomechanical concepts to the interaction of photons and phonons in an extended waveguide. We introduce a real-space picture and argue which coupling terms may arise in leading order in the spatial derivatives. This picture allows us to discuss quantum noise, dissipation, and the correct boundary conditions at the waveguide entrance. The connections both to optomechanical arrays as well as to the theory of Brillouin scattering in waveguides are highlighted. Among other examples, we analyze the ‘strong coupling regime’ of continuum optomechanics that may be accessible in future experiments.
Highlights
Cavity optomechanics [1] is a very active research area at the interface of nanophysics and quantum optics
Even though the vast majority of optomechanical systems rely on a cavity, there are a number of implementations that evade this paradigm
Optomechanical effects are observed in waveguide-type structures, where both the optical field and the vibrations propagate in 1D, with the potential to uncover new classical and quantum phenomena
