Integrated bi-directional transceivers for Access applications based on a cost-effective PLC hybridized platform

摘要

In the quest for cost-effective bi-directional transceivers for the fibre-to-the-premise (FTTP) applications, this article describes the development of such devices manufactured on the Planar Lightwave Circuit (PLC) platform. The transceiver consists of the optical head, which receives, filters and detects the optical signals and the electronics, which processes these signals according to specific protocols. In this article, the realization of the optical head (known as a diplexer or triplexer) will be the main focus, with key results, such as the manufacture of the hybridization platform, the design and performance of the optical filters and the hybridization on the laser and photodiodes, presented. The challenges faced in the development will be described as well as the next steps to achieving the final product.
