Simplification in preparing fiber ends to attach small mirrors

Abstract

A simplified way to make a good surface for contacting a mirror to an optical fiber by heating the fiber end is described. The technique causes the deposited core and cladding of a fiber made by the modified chemical vapor deposition method to bulge slightly, providing a pivoting surface for orienting the mirror. The method is applicable to the fabrication of high finesse fiber Fabry–Perot interferometers.
