Abstract:
A method for delaying optical pulses comprising the steps of:coupling said optical pulses into a waveguide comprising electro-optically active material, said waveguide having a chirped distributed Bragg reflector formed within said electro-optically active material that reflects said optical pulses at a turning point within said waveguide and said electro-optically active material having an index of refraction; applying an electric field to said electro-optically active material to change said index of refraction of said electro-optically active material so as to change said turning point of said chirped distributed Bragg reflector, the change of turning point proportional to the amount of desired pulse delay; and, coupling said optical pulses reflected from said chirped distributed Bragg reflector out of said waveguide.
