Tunable chromatic dispersion and dispersion slope compensator utilizing a virtually imaged phased array and a rotating grating

摘要

A tunable chromatic dispersion and dispersion slope compensator that utilizes a Virtually Imaged Phased Array (VIPA), a rotating transmissive diffraction grating, and a mirror with different curvatures for different cross-sections is disclosed. The compensator in accordance with the present invention provides simultaneous tunable compensation of chromatic dispersion and dispersion slope utilizing a single apparatus. The amount of compensation is accomplished by rotating the transmissive diffracting grating and/or translating the mirror. A system which utilizes the compensator is thus cost effective to manufacture.
