A comparative study of three-wave, four-wave and higher-order-wave parametric processes
Abstract
This report examines three-wave, four-wave, and higher-order-wave parametric processes taking into account pump depletion. The theory for both three-wave forward traveling wave (FTW) and backward traveling wave (BTW) interactions is reviewed. A comprehensive comparison of three possible down conversion systems and three up conversion systems is made based on a common set of system parameters consisting of input pump excitation and the ratio of input signal to pump photon flux. Of the down conversion systems, the system consisting of a BTW at the signal frequency and a FTW at the pump frequency most efficiently transfers energy from the pump wave for any given level of pump excitation or ratio of signal/pump photon flux. In up conversion, the system consisting of two forward traveling waves at the pump and signal frequencies is the most efficient.
