OPTICAL FILTER DEVICE EMPLOYING A PROGRAMMABLE DIFFRACTIVE ELEMENT AND THE CORRESPONDING SPATIAL SPECTRAL BAND ROUTER AND CHROMATIC DISPERSION COMPENSATION DEVICE

摘要

The invention relates to an optical filter comprising at least one input optical fiber and at least one optical fiber of sortie.selon the invention, such a device comprises means of transfer, to at least one of the output optical fibers, of at least a spectral band of at least one signal with multiple wavelengths incident by at least one of said input optical fibers, said transfer means using at least one programmable diffractive element located on an optical path between the said input optical fibers and the said optical fibers sortie.l' invention also relates to a router of the spectral bands and a device for the chromatic dispersion compensation implementing such a filtering device.
