Gi. Stegeman et al., CHI((2)) CASCADING PHENOMENA AND THEIR APPLICATIONS TO ALL-OPTICAL SIGNAL-PROCESSING, MODE-LOCKING, PULSE-COMPRESSION AND SOLITONS, Optical and quantum electronics, 28(12), 1996, pp. 1691-1740
Cascading is the process by which the exchange of energy between optic
al beams interacting via second order nonlinearities (chi((2))) leads
to various effects such as nonlinear phase shifts, the generation of n
ew beams, all-optical transistor action, the formation of soliton-like
(solitary) waves, etc. Here we review the fundamentals of the process
es and discuss experimental verification of the effects and various re
lated applications.
