Switchable optical dispersion compensator using Bragg-grating

摘要

A switchable dispersion compensator comprises an input waveguide for carrying an optical signal having dispersion. Further, a wavelength-selective switch is provided that has a chirped Bragg grating disposed proximate to the input waveguide. The wavelength-selective switch when in an "on" position couples the optical signal into an output waveguide. When the wavelength-selective switch is in an "off" position, the optical signal continues propagating in the input waveguide.
