Title: Focusing system based on chalcogenide microlenses attched to optical fibers

Abstract: Arsenic chalcogenide microlenses (As2S3) produced by an original procedure have been used for focusing the red - infrared laser light direct through an optical fiber. The microlenses with diameter in the range 150 - 400 mu m were glued on the optical single-mode fiber ends by Canada balm under optical microscope, The focusing effect of the microlenses was investigated in a stereomicroscope, and the focusing quality was studied with the radiation of a He-Ne laser.

Key words: chalcogenide; As2S3; lenslet; spherical length; convex lens; optical focusing; lens-optical fiber system
