Abstract
A signal channelizer () includes an input waveguide () carrying an inputted signal () having a plurality of wavelengths. The input waveguide () has an input port () for receiving the inputted signal (). A plurality of ring resonators () for wavelength selection are arranged in parallel and coupled along the input waveguide () for receiving the inputted signal () from the input waveguide (). The plurality of ring resonators () passes a selected wavelength signal to their respective output end (). An output waveguide () passes a desired signal from one or more ring resonators (). The output waveguide () is tapped with couplers () for providing a desired signal to feed the output end (). A detector () associated with the output end () of each ring resonators () produces the desired RF output signal () representative of the desired RF band.
