摘要

Precisely aligned transparent fused-silica (SiO_2) microspheres 2.5 μm in diameter were nonthermally welded to silicone rubber by 157 nm F_2-laser-induced photochemical modification of the silicone into silica. A short exposure to the F_2 laser of ～10 mJ/cm~2 single-pulse fluence, 10Hz pulse repetition rate and 600 pulses was required for sufficient photochemical welding. The welding strength depended on the extent of the silica formation, which was controlled by F_2 laser exposure. Silica formation occurred even in silicone underneath the microspheres due to the F_2 laser decomposition of oxygen molecules dissolved in the silicone. A cross-sectional atomic force microscope image of silicone underneath the microspheres after welding revealed that a large contact area between the silicone and the microspheres was formed. After welding, the aligned silica microspheres were butt-coupled to a tapered silica optical fiber ～2.5 μm in diameter for optical waveguide applications. The alignment was found to have the capability of guiding red (635 nm)-wavelength light.
