Abstract

We consider the transmission properties of a novel type of optical filter, based on a periodic array of curved coupled optical waveguides in which the curvature varies periodically with propagation distance. For carefully chosen curvature profiles, this system exhibits transmission resonances that arise in direct analogy to the dynamic localization of electrons in a periodic potential in a periodic ac electric field. We demonstrate its use as a bandpass optical filter and show how the curvature profile can be adjusted to tailor the transmission of the structure.
