Abstract

Refractive-index discontinuity in optical connectors causes Fresnel reflection, which results in unstable laser diode oscillation. This paper outlined the theoretical selection of the optimum refractive index for the matching material necessary to minimize this reflection. Moreover, cerium oxide has been found to be suitable for final polishing of fiber endfaces. A return loss greater than 40 db has been experimentally confirmed to be possible for the 0. 85-1. 3 mu m wavelength. The techniques employed are found to be satisfactory for practical field use.
