Abstract
Embodiments of the inventions described herein comprise a device and method for manipulating an optical beam. The method comprises propagating an optical beam through a waveguide in proximity to a resonant cavity and pumping the resonant cavity with sufficient optical power to induce non-linearities in the refractive index of the resonant cavity. The method further comprises tuning the resonant frequency band of the resonant cavity with a modulation signal such that the optical beam is manipulated in a useful way.
