中文摘要： 表面等离激元感应透明（PIT）类似于经典的电磁感应透明（EIT）， 在非线性光学和集成光子器件领域具有重要应用。目前国际上在PIT及其应用领域的实验研究中存在的难题是，难以实现在平行于金属微纳结构表面的平面内片上集成PIT，以及在平行于金属微纳结构表面的平面内泵浦的全光超快速低功率可调谐片上集成PIT。本项目探索利用单个表面等离激元复合微腔、以及表面等离激元耦合腔等方法来实现平面内片上集成PIT；探索利用量子局域效应增强非线性、表面等离激元共振增强非线性、局域场增强非线性等方法实现具有超快响应和大三阶非线性极化率的纳米复合材料的途径；探索实现平面内泵浦的全光可调谐片上集成PIT的方法，并实现超快时间响应和低泵浦光功率；探索平面内泵浦的全光可调谐PIT在微纳光开关、可调谐滤波器和波分复用器等微纳集成光子器件中的应用。

英文摘要： Just like the classical electromagnetically-induced transparency, plasmon-induced transparency (PIT) has important applications in fields of nonlinear optics and integrated photonic devices. Nowadays,the international problem in the field of PIT and applications lie in that it is difficult to realize chip-integrated PIT in the plane parallel the surface of metallic microstructures, and ultrafast and low-power all-optical tunable on-plane chip-integrtaed PIT based on on-plane pump method.This project explores the method of realizing on-plane chip-integrated PIT by using single surface plasmon composite microcavity, and surface plasmon coupled microcavities. This project explores the approach to realizing nanocomposite materials having ultrafast response time and large third-order nonlinear susceptibility by using quantum confinement enhancing nonlinearity, resonant excitation of surface plasmon polariton enhancing nonlinearity, and local filed enhancing nonlinearity. This project explores how to realize all-optical tunable chip-integrated PIT based on on-plane pump, having ultrafast time respoanses and low pump power. This project explores the applications of all-optical tunbale chip-integrated PIT based on on-plane pump in the field of nanoscale integrated photonic devices, including all-optical switching, all-optical tunable filter, and wavelength-division multiplexing.
