Title: Optical fiber coupling to a laser diode through chalcogenide microlenses

Abstract: Microspherical lenses (50 divided by 800 mu m in diameter) based on glassy As(2)S(3), have been produced by a special flame melting technique. The microlenses have been used for focusing the red - infrared laser light at the end of an optical fiber. Microlens arrays have been produced and applied in coupling optical fibers to a light remitting diode (LED), in order to increase the intensity. A double ball lens coupling scheme has been designed and manufactured.

Key words: Microlens; IR; Optical fiber; Chalcogenide; As(2)S(3)
