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.

该项目的目标是：1)制备光学质量好的特定共轭聚合物单晶薄膜；2)制备定向耦合器等特殊通道波导结构；单晶薄膜中的马赫-曾德尔干涉仪和feb - Perot等；iii)利用时间和波长分辨测量研究这些特殊结构中的非线性光学效应。特定的共轭聚合物，如聚二乙炔，已知具有极大的非线性折射率和低吸收系数在其非共振域。
