Abstract

Microspherical lenses (50 ÷ 800 μm in diameter) based on glassy As 2S 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..
