OptoMécanique avec des cristaux photonique



Optomechanics deals with the interaction of light with a mechanical oscillator. It utilizes the coupling between light and the geometry of a mechanical oscillator to read or tailor the mechanical motion of the oscillator. This coupling is stronger at the nano-scale because of the very small mass of nano-mechanical oscillators.


The Optomechanics with photonic crystals investigates the nano-optomechanics of suspended photonic crystal membranes. Depending on the arrangement of holes, the membrane can either act as a deformable end-mirror in a conventional Fabry-Perot cavity or include a cavity of diffraction-limited volume that simultaneously confines both phonons (i.e. mechanical vibrations) and photons. These structures combine cavity enhancement and low mass and thus exhibit strong mechanical coupling to light. In particular, optomechanical resonators formed by conventional photonic crystal membranes sustain mechanical modes in the GHz frequency range, which are highly coupled to light.
