Abstract

The connection of two optical fibers is a problem of great interest in all the application areas of fiber optic laser systems.It has been widely investigated in the field of optical communications,where low power laser diodes are usually employed.Less attention has been devoted so far to the problem of fiber interconnections with medium and high power laser sources,which are used for instance in the industrial and medical fields. We have analysed the possibility of using lens ended fibers to improve the performances of conventional connections,through the relaxation of the positional tolerances.Two types of connections (a) bulb ended fiber to flat ended fiber ; (b) bulb ended fiber to bulb ended fiber are considered,in the case of eaual fibers as well as in the case of fibers with equal core diameter and different N.A. These new connections have been experimentally tested,and their performances compared with usual flat-flat connection.It has been shown that bulb ended fiber connections constitute an effective improvement with respect to the conventional ones.
