Abstract
Aspects of the present disclosure describe optical structures and devices, and more particularly to improved, tunable optical structures including optical gratings that are dynamically affected and/or tuned by acousto-optic or electro-optic mechanisms.
Claims54
A method of forming an optical structure comprising:
- providing an optical waveguide having a light guiding core;
- inducing dynamic index perturbations into the optical waveguide, said dynamic index perturbations sufficient to affect the emission of light traversing the optical waveguide, said emission in a direction out-of-plane relative to the waveguide.
An optical device comprising:
- an optical waveguide including a light guiding section;
- a dynamic index perturbation generator configured to dynamically generate index perturbations in the light guiding section;
- such that upon activation of the dynamic index perturbation generator and the generation of index perturbations in the light guiding section, light traversing the light guiding section is emitted in a direction out-of-plane relative to the light guiding section.
An optical phased array comprising:
- a plurality of emitters, each individual emitter including;
- an optical waveguide including a light guiding section;
- a dynamic index perturbation generator configured to dynamically generate index perturbations in the light guiding section.
