ELECTROHOLOGRAPHIC WAVELENGTH SELECTIVE PHOTONIC SWITCH FOR WDM ROUTING

摘要

A device (110) for switching light of one of more discrete wavelengths to on e or more output conduits (106). The device (110) includes fibers (a-b) for ea ch wavelength and for each output conduit (106), an electroholographic switch (100aa-ab) for switching a controllable portion of the light of each wavelength to each output conduit (106), the electroholographic switches (100aa-bb) of a common output conduit (106) being optically coupled, the electroholographic switches (100aa-bb) of a common wavelength being opticall y coupled.
