Abstract

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 thistechnique will make it possible to polymerize monomer. As comonomers p-tert-Buthylclix[8]areneacrylate (CA-Ac) and Pentaerythritoltriacrylate (PETA) (molar ratio: CA-Ac : PETA= 1:1) were used. 3-(2'-Benzimidazolyl)-7-Diethylamino-coumarin (BIDC) as a photosensitizer and Diphenyliodoniumhexafluorophosphate (DIHP) as a photo-initiator were also used. The mixed PMMA and chloroform solution of those were cast on a substrate. Focused 800nm femtosecond pulsed laser beam by objective lens was scanned perpendicularly to the substrate. Thus we obtained a 3D polymer waveguide and confirmed the confinement of a 1300nm wavelength light.
