Abstract:
An optical pulse compressor for compressing in time optical pulses from a pulse source, said compressor comprising:a first section of optical waveguide including a transmissive waveguide Bragg grating for providing positive dispersion to said optical pulses, said first section being nonlinear optical waveguide characterized by a second order refractive index N.sub.2 ;optically coupled to said first section of optical waveguide, a second section of optical waveguide optically coupled to a component for providing negative dispersion to said pulses, said second section being linear optical waveguide characterized by a second order refractive index N.sub.2 ' less than 0.1 N.sub.2, whereby a transform limited pulse transmitted through said first section including said Bragg grating and said second section including said component is compressed in time.
