Abstract

Optical waveguide systems useful as frequency-selective reflectors, filters, or resonators. Each system utilizes at least one grid fan means having elongated grating strips arranged in a fan-like manner and adapted to have a continuously variable grating constant. At least one waveguide is spatially located in adjacent relationship to a given grid fan in each system.
