Optomechanics in photonic and phononic crystals


Controlling the properties of micro- and nano-optical, and mechanical systems, has recently become possible following advances in nanofabrication techniques. This is the case of optical micro-cavity, micro-lasers, and optomechanical systems to cite a few. In this proposal we will investigate micro-and nano-optical devices with special attention to optomechanical systems. Here the strong interaction between optical fields (photons) and acoustic waves (phonons) leads to classical and quantum phenomena such as electromagnetic induced transparency, and mechanical ground state cooling, which are both technological and scientific relevant. Our devices will be based on photonics and phononic crystals. We believe that developing a dedicated instrumentation for fabricating and testing such systems will contribute for the expansion and establishment of nanophotonics in São Paulo. (AU)
