Abstract

The paper presents an analysis of thermo-optic phase shifters in silicon-on-insulator (SOI) waveguide structures. It gives recommendations to provide high tuning characteristics at minimum power requirements. Then, this analysis is applied to the description of a novel type of reconfigurable optical add/drop multiplexer (ROADM) utilizing multi-reflector (MR) beam expanders and thermo-optic tuning in SOI structures. It is intended for use in high dense wavelength-division-multiplexing (HDWDM) flexible fiber-optic networks having multi-hundreds wavelength channels and advanced ITU grids (12.5 GHz, 25 GHz, 50 GHz).

摘要

本文对绝缘体上硅（SOI）波导结构中的热光相移器进行了分析。它给出了在最小功率需求下提供高调谐特性的建议。然后，该分析被应用于描述一种新型的可重构光分插复用器（ROADM），该复用器利用多反射器（MR）光束扩展器和SOI结构中的热光调谐。它旨在用于具有数百个波长通道和先进ITU网格（12.5 GHz、25 GHz、50 GHz）的高密度波分复用（HDWDM）灵活光纤网络。
