RIA: Single Crystal Waveguide Structures of Conjugated Polymers: Preparation and Nonlinear Optical Properties

该项目的目标是：（一）编制 具有良好光学质量的单晶薄膜， 共轭聚合物，ii）制备特殊的 通道波导结构 耦合器，马赫-曾德尔干涉仪和费布里- Perot标准具等， iii）研究这些特殊的非线性光学效应 使用时间和波长分辨的结构 测量. 特定的共轭聚合物， 因为已知聚二乙炔具有极高的 大非线性折射率沿着 非共振吸收系数 域.

The objectives of this project are: i) preparation of good optical quality single crystal films of specific conjugated polymers, ii) preparation of special channel waveguide structures such as directional coupler, Mach-Zehnder interferometer and Febry- Perot etalon etc. from the single crystal films and iii) study nonlinear optical effects in these special structures using time and wavelength resolved measurements. Specific conjugated polymers such as polydiacetylenes are known to have extremely large nonlinear refractive indices along with low absorption coefficients in their off-resonant domains.
