    摘要: An integrated-optic attenuator/equalizer device comprising a photorefractive substrate, at least one optical waveguide channel formed in the substrate, at least one diffractive-Bragg grating formed in the substrate, and a diffractive-Bragg grating modulator that is capable of modulating the diffractive Bragg grating(s). The diffractive-Bragg grating(s) intersects the optical waveguide channel. When a diffractive-Bragg grating formed in the substrate is modulated, at least a fraction of light of a wavelength associated with the modulated diffractive-Bragg grating is re-directed by the modulated diffractive-Bragg grating, thereby preventing the re-directed fraction of light from arriving at the output of the optical waveguide channel. Multiple diffractive-Bragg gratings may be implemented in the integrated-optic device, each having a particular wavelength associated therewith, and the diffractive-Bragg gratings may be simultaneously or independently modulated to control the fractions of light of different wavelengths that arrive at the output of the optical waveguide channel.
