Stimulated Mach-wave phonon emission: Towards broadband phonon emitters and receivers

We review the physics of photon-phonon coupling in guided wave systems, and discuss new opportunities for information transduction aorded by nanoscale connement of light and phonons within a novel class of optome- chanical waveguide systems. We present a fundamental analysis of optical forces generated through nanoscale light-matter interactions, and use these insights to develop new approaches for broadband signal processing via optomechanics. Recent experimental results will also be discussed.
