Abstract

PURPOSE:The reduction in Fresnel reflection loss and the improvement in stability are achieved by using a focusing lens provided with a reflecting surface at part of its meridional plane and disposing an incident side optical fiber to one end thereof and exit side optical fibers to the other end.
