| Outline of Final Research Achievements |
We have developed a flexible optical wave guide that enables close proximity to various peripheral environments by incorporating an optical integrated device in a polymer thin film. A Mach-Zehnder (MZ) optical wave guide was embedded by focused proton beam (Proton Beam Writing; PBW) in a freestanding polymer thin film with a thickness of about several tens of micrometers. A local refractive index change was induced in the deep part of the thin film by utilizing high density energy around the Bragg peak of focused proton with energy from 0.5-3 MeV. An optical wave guide was mounted on a seamless thin film by setting the micro fabricated part as the core and cladding part of surrounding parts. Electrodes were applied to a part of the MZ wave guide, and the optical switching function by thermo-optic effect was also confirmed. According to the present technology development, it is possible to realize optical wave guide mounting inside arbitrary functional polymers.
