Generally, optical polymer waveguides have been fabricated by using a combination of photolithography and reaction ion etching. However those processes require much time and effort. Here, we propose two-photon-absorbed photopolymerization for waveguide fabrication because this technique will make it possible to polymerize monomer site-selectively. As comonomers p-tert-Buthylclix[8]arene acrylate (CA-Ac) and Pentaerythritol triacrylate(PETA)(molar ratio: CA-Ac : PETA = 1:1) were used. 3-(2′-Benzimidazolyl)-7-Diethylamino coumarin(BIDC) as a photo-sensitizer and Diphenyl-iodonium hexafluorophosphate(DIHP) as a photo-initiator were also used. The chloroform solution of those was cast on a substrate. Focused 800nm femto-second pulsed laser beam was exposed. Laser beam was scanned perpendicularly to the substrate. Thus we obtained a polymer waveguide and confirmed the confinement of a 1300nm wavelength light.
