  • Method for collective production of microlenses at the tip of an optical fiber assembly such as a fiber tape
    Patent number: 6768837
    Abstract: A method for the collective production of microlenses at the end of a set of aligned optical fibers. The method consists in heating the end of all the fibers by means of an electric arc in order to form the microlenses, the plane in which the ends of the fibers are situated being distant from the line of the hottest points in the electric arc in order to round their end homogeneously. Useful for making optical and optoelectric modules.
