Paper Abstract

We present experimental characterization of periodically-poled KTP waveguide studying the process of second harmonic generation. Spatial and spectral properties of three types of the nonlinear processes (Type 0, I, and II) have been observed simultaneously utilizing the first, second, and third harmonics of the spatial nonlinear modulation. Experimental results have been interpreted using a model based on scalar finite elements method, which has been adopted in order to calculate spatial mode profiles, propagation constants, and frequencies of the interacting fields. Correlations between spatial and spectral properties of the fundamental and second- harmonic fields have been revealed. Individual nonlinear processes can be switched on and off combining spatial and spectral filtering. Also the influence of waveguide parameters to the second-harmonic spectra has been addressed.
