LIGHT-INDUCED SELF-WRITTEN POLYMER OPTICAL WAVEGUIDE FOR SINGLE-MODE PROPAGATION AND FOR OPTICAL INTERCONNECTION

利用单模光纤在光聚合树脂混合物溶液中制备了光诱导自写入（LISW）聚合物光波导。为了实现直波导芯，在芯形成之前进行预UV处理。通过适当控制混合物中树脂的比例，首次实现了1310 nm激光的单模传输。利用该技术实现了两单模光纤之间的光互连，并利用几种在写入波长处吸收很小的生色团实现了LISW波导技术制备功能光波导。利用LISW波导技术成功地制作了透明波导和功能波导的串联嫁接波导，通过薄玻璃隔板后芯层没有任何偏移。

Light-induced self-written (LISW) polymeric optical waveguides were fabricated in a photopolymerizing resin mixture solution using a single-mode optical fiber. In order to realize a straight waveguide core, a pre-UV treatment was performed before core formation. Single-mode propagation of laser light at 1310 nm was realized by appropriately controlling the ratio of the resins in the mixture for the first time. Moreover, optical interconnection was demonstrated between two single-mode fibers was demonstrated based on this technology.Furthermore, LISW waveguide technique for the fabrication of functional optical waveguide was realized using several chromophores, which have very little absorption at a writing wavelength. Serially grafted waveguides consisting of transparent and functional waveguides were successfully fabricated using LISW waveguide technique without any offset of core after passing through the thin glass partitions.
