Hybrid coherent-optical, RF signal channelizer

摘要

An optical channelizer system that is adapted to provide instantaneous RF signal channelization at frequencies on the order of 100 GHz or more into channels having bandwidth as small as a few megahertz. In order to improve the channel resolution the optical channelizer system is formed from a plurality of parallel subchannelizers, for example, twenty-five parallel sub channelizers which can provide 1 GHz channel spacing and 40 MHz signal resolution.
