Abstract

We have shown that very large nonlinear shifts ranging from pi/4 to pi/2 observed at relatively modest input intensities in single-crystal cored fibers of 4-(N,N-dimethylamino)-3-acetamidonitrobenzene (DAN) have their origin in the cascading of two second-order nonlinear processes: second-harmonic generation followed by down-frequency conversion. The nonlinear shifts and corresponding n(2) values extracted from independent observations of self-phase modulation and direct interferometric measurements are as large as 10(-12) cm(2)/W at relatively modest input intensities from 30 to 60 MW/cm(2). The cascading origin of largen(2) values was fully confirmed by z-scan measurements performed on asingle DAN crystal.
