Abstract
We propose a photonic radio-frequency (RF) channelization scheme which can slice the frequency spectrum into different subchannels through shaping the optical sampling pulse of each subchannel. An optical pulse shaper, which is composed of two cascaded multi-tap optical pulse shapers, is used in each subchannel to shape the sampling pulse. The principle of proposed scheme is theoretically analyzed, and experimentally verified. Through shaping the sampling pulse, the channel responses with 500 MHz bandwidth and center frequency of 7.5 GHz/8.5 GHz are experimentally measured.
