Abstract

The stringent alignment requirements for connecting graded index multimode optical waveguides have resulted in detachable connectors which are mostly laboratory curiosities and are not suitable for app-lication in the field. Achieving accurate alignment does not necessarily guarantee less than 1.0 dB coup ling loss. In this paper the interconnection problem is analyzed from a model which is concerned with the fiber transmission properties thus permitting the analysis to deal with losses in the system. Losses due to misalignments are shown to be dependent on power distribution in the waveguides. The common inter connection concepts of end to end joining and a simple collimating lens are analyzed. Expected losses for these systems make a 1.0 dB detachable connector difficult to achieve. A new concept which forms an index of refraction fluid into a compound lens is shown to surmount the problems encountered in typical connector systems.
