The main goals of the project are theoretical and experimental investigations of networks of coupled Integrated Micro Resonators (IMR) and Photonic Crystal Resonators (PCR). It is proposed to design, fabricate, and investigate 1D and 2D networks of IMR/PCR in linear and nonlinear operation modes as new implementations of discrete optical conservative and dissipative systems.IMRs will be fabricated from silica glass (pure for conservative, doped by Er-ions for dissipative systems) or from LiNbO3 membranes (for dissipative systems). PCRs will be produced in LiNbO3 membranes, which exhibit large quadratic nonlinearities. Two regimes of pumping will be used: incoherent (in case of Er-doped IMR networks) and coherent (IMR in LiNbO3 and PCR networks) optical pumping. Parametric processes based on quadratic and cubic nonlinearities for IMR/PCR networks will be used for a coherent amplification.First, the dispersion relations describing the signal propagation in the linear operation mode will be investigated. Second, stable temporal pulses and stable spatial localized structures will be the subject of research in the case of high signal intensities. Third, stable spatial-temporal localized optical structures in dissipative discrete systems (resonator networks with external pumping) will be investigated experimentally.
