Abstract

Silica-on-silicon is one of the best materials structures currently considered for production of integrated optical devices, in particular for telecommunication and signal processing applications. Deposition of silica films can be advantageously attained by the sol-gel technique, which permits both a great flexibility in the refractive index definition and the possibility of doping with rare earth ions. In this work, we designed and modeled an integrated optical duplexer, intended as a component of a fully- integrated erbium-doped optical amplifier, operating in the third telecommunication window. The guiding structures are of the strip-loaded type, to be realized by the sol-gel technique onto a buffered silicon substrate. Design optimization and modeling was carried out by a software package which was developed on purpose in MATLAB environment, mainly based on the Effective Index Method. Here we report a general design procedure for the above said component, which takes into account industrial production requirements as well as device's performance.
