Optical channelizer for W-band detection

A method for signal channelizing comprising:

• receiving, by an input waveguide, an inputted signal having a plurality of wavelengths including a desired wavelength, wherein the inputted signal comprises a single carrier signal;
• filtering the inputted signal through each of a plurality of ring resonators to pass a selected wavelength signal to a respective output end, wherein the plurality of ring resonators are arranged in parallel and coupled at spaced apart locations along the input waveguide for receiving the signal;
• receiving, by two control waveguides, two signals having wavelengths that differ from the desired wavelength by a first predetermined amount and a second predetermined amount respectively;
• and
• producing, by a plurality of detectors, channelized RF output signals representative of desired RF bands, wherein each of the plurality of detectors is coupled to a respective output end of one of the ring resonators and to one of the two control waveguides.
