  • Article comprising means for optical pulse reshaping
    Patent number: 6201916
    Abstract: In an optical fiber communication system a pulse reshaper can transform a distorted input light pulse into a reshaped output light pulse. The disclosed pulse reshaper is an all-optical pulse reshaper that comprises an optical waveguide having an effective length, the waveguide connecting the input and the output and comprising optical non-linear material, with a periodic variation of an effective refractive index of the optical waveguide. The optically non-linear material and the periodic variation are selected such that the reshaped output light pulse is a substantially transform-limited output light pulse.
