A polymeric waveguide film was manufactured by spinning the materials on ITO, and the two-photon initiated photopolymerization(TPIP) was carried out successfully in the waveguide film. Consequently, an approach using TPIP is demonstrated for fabrication of grating in a thin polymeric film possessing waveguide properties. The results show that the resulted grating can manipulate and couple light.展开更多

The results of the study show that the two photon polymerization of TMPTMA can be initiated by means of 4,4 bis(di n butylamino) E stiebene(BDBAS) under 600 nm strong laser. The light source that we used for the two photon polymerization is a YAG pumped dye laser whose oscillating wavelength repetition rate and single pulse energy are 600 nm, 10 ns and 15 mJ, respectively. The peak power density of radiation light tight focused by means of bojective lens is 3.8 GW/cm 2. The relative mechanism of the polymerization is discussed. [WT5HZ]展开更多
