Second-order cascading as the origin of large third-order effects in organic single-crystal-core fibers.
We have identified cascading of second-order nonlinear processes as the origin of previously reported, very large nonlinearities measured by self-phase-modulation experiments in organic single-crystal-core fibers of 4-(N,N-dimethylamino)-3-acetamidonitrobenzene.
