The dissipative nature of the optical resonators requires loss compensation through some pump process. The nonlinear response of the resonator in combination with the feedback causes a bunch of new effects, including multistability and pattern formation [1, 2]. In this work the nonlinear effects have been investigated in resonators formed in Periodically Poled Lithium Niobate (PPLN) exhibiting strong second order nonlinearity. The final goal of the tests is to demonstrate fast memory operations in optical waveguide resonators based on PPLN samples. A theoretical model has been developed in order to estimate the influence of different parameters on the system performance. Theoretical predictions have been compared with the experimental results.
