Abstract : Parametric signal processing technology is described. Work on mixer synthesis, gain and conversion efficiency, signal multicasting and sampling is outlined in detail. The technology limits and its applications in multiplexing, demultiplexing, amplification, conversion and signal delay construction are described. Achievements include (1) longitudinal nonlinear waveguide characterization which resulted in unprecedented mixers surpassing 20 THz in bandwidth and greater than 20 dB gain, (2) ability to copy THz signals with impunity to tens of replicas; (3) all-optical delays greater than 1.9 us; (4) 10's of THz-fast all-optical sampling of signals and (5) an original fully scalable MPASS parametric processor for detection of THz signals availing access to all the (ultra high speed) data all the time at 640 Gbps over 100 km transmission distance.
