Parametric Photonic Channelized RF Receiver
A new class of photonic channelized radio-frequency
(RF) receiver is proposed and demonstrated. The new device relies
on generation of high fidelity signal copies by wavelength multicasting
in a self-seeded, two-pump parametric mixer. Signal copying
to widely spaced wavelengths enables channelization of the full RF
bandwidth using a single periodic filter. The channelization uses
freely tunable frequencies of newly generated copies and eliminates
the need for construction of a dense, narrowband filter bank. The
new concept is demonstrated by channelization of four subcarrier
channels with 1-GHz spacing and greater than 20-dB extinction
ratio between extracted channels.
