Abstract
An optical system has a beam-steering device having a planar waveguide region between a tapered incoupler and a tapered outcoupler that respectively define opposing incoupler and outcoupler facets of the BS device. Each region has a substrate, a subcladding layer over the substrate, a core layer over the subcladding, and a top cladding layer over the core. Within the incoupler, at least one of the subcladding and the top cladding has a material having a refractive index that varies with an applied field (e.g., an electric field) applied at the incoupler. The optical system also has a field-applying device that applies the applied field at the incoupler, an output detector that generates a feedback signal based on detected outgoing light output from the outcoupler, and a controller that controls the field-applying device based on the feedback signal to alter the light output from the outcoupler.
