Abstract

In this paper, we show and analyze, for the first time, the static performance of integrated multi-stage cascade and tree spectral amplitude OCDMA en/decoders (E/Ds) which are fabricated in the low loss Si3N4–SiO2 material system. Combined with incoherent broad spectral sources these E/Ds enable cost-effective node deployment in an OCDMA passive optical network architecture. We discuss the design of a crucial component, namely the 2x2 3dB multi-mode interference (MMI) coupler. Finally we show measured spectral codes of two-stage E/Ds and compare these with modeled ones.
