Abstract

Second harmonic generation (SHG) was the first nonlinear optical process investigated. In addition to the energy exchange between the fundamental and second harmonic waves, there is also a nonlinear phase shift imposed on the fundamental when the waves are not phase matched. Such cascaded second order effects can mimic large third order nonlinearities and have applications in all-optical switching devices.1 It was previously shown that positive nonlinear phase shifts were possible with minimal loss to the harmonic.1 In this study, we demonstrate how to get arbitrary nonlinear phase shifts, also with minimal loss to the harmonic, by tailoring (with temperature) and verify the results by measuring the wavevector mismatch along LiNbO3 waveguides. This extends the utility of cascading to effects such as the phase-induced transitions in soliton collision behavior, etc.2
