TLDR
High-speed operation dominated by just optomechanical effects of reconfigurable optical filters is demonstrated, and independent control of mechanical and optical resonances of the authors' structures is demonstrated.Abstract:
Nanoscale optomechanical systems offer a route to using optical forces for a range of devices based on photonic structures. Deotare et al. present a reconfigurable optical filter based on coupled silicon photonic crystal nanobeam cavities that can overcome thermo-optic effects at high frequencies.read more

Applications of cavity optomechanics
TL;DR: Cavity-optomechanics as discussed by the authors aims to study the quantum properties of mechanical systems and use feedback forces such as radiation pressure to cool the mechanical mode of interest into the quantum ground state and create non-classical states of mechanical motion.

Temporal coupled-mode theory for the Fano resonance in optical resonators
TL;DR: A theory of the Fano resonance for optical resonators, based on a temporal coupled-mode formalism, is presented and it is shown that the coupling constants in such a theory are strongly constrained by energy-conservation and time-reversal symmetry considerations.
