Abstract :
A staring wideband RF channelization using parametric multicasting and spectral slicing via a periodic optical filter with 32 implemented channels is presented. Parametric multicasting is technique which replicates and spectrally translates an RF signal via optical nonlinear processes. Injection locking of the pump and signal lasers to a single master laser was implemented to improve performance and stabilize pump and signal spacings. Sensitivity and dynamic range in each channel is also discussed.
