Discrete spatio-temporal dynamics in nonlinear microstructured resonators

该项目的主要目标是耦合集成微谐振器（IMR）和光子晶体谐振器（PCR）网络的理论和实验研究。作为分立光学保守和耗散系统的新实现，我们提出设计、制备和研究一维和二维IMR/PCR网络，IMR将由石英玻璃（纯的用于保守系统，掺Er离子的用于耗散系统）或LiNbO 3膜（用于耗散系统）制备。PCR将在LiNbO 3膜中产生，其表现出大的二次非线性。将使用两种泵浦方式：非相干（在掺Er的IMR网络的情况下）和相干（LiNbO 3和PCR网络中的IMR）光泵浦。基于IMR/PCR网络的二次和三次非线性的参数过程将用于相干放大。首先，将研究描述线性操作模式下信号传播的色散关系。第二，在高信号强度的情况下，稳定的时间脉冲和稳定的空间局部结构将是研究的主题。第三，将实验研究耗散离散系统（具有外部泵浦的谐振器网络）中稳定的时空局域光学结构。

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.
