摘要：
A channelizer for optically channelizing RF signals modulated onto an optical carrier by optically separating the RF signals and mapping the RF signals by way of an optically dispersive element 22, such as a diffraction grating. In an alternate embodiment of the invention, two stages of optical filters elements are provided in series to perform sequential channelization. Bragg reflection gratings 31,33 are used for coarse filtering into predetermined bands while Fabry-Perot filters tuned to specific sub-bands of the Bragg reflection gratings 31, 33 are used for channelization. In alternate embodiments of the invention, a silica planar waveguide and a optical splitting device, such as a Talbot splitter, are used.
