摘要
文章介绍了一种具有升级能力和动态增益均衡的低成本可重构光分插复用器(ROADM)。该模块由平面阵列波导光栅、光开关集成可调衰减器(SiVOA)、环行器、探测器、耦合器以及隔离器构成。SiVOA的灵活应用实现了波长的双向传输并降低了模块成本。通过调整SiVOA,可以实现任意单波长或多波长的上下路及功率调节。文章给出了模块的基本工作原理及指标测试结果。
A low-cost reconfigurable optical add/drop multiplexer （ROADM） with system upgrade capability and dynamic gain equilibrium is studied. This module consists of planar Arrayed-Waveguide Grating （AWG）, Switch Integrated Variable Optical Attenuator （SiVOA）, circulator, tap PD, coupler and isolator. The flexible application of SiVOA contributes to the realization of the two-way transmission of wavelengths and module cost reduction. Optical signals with single or multiple wavelengths can be added/dropped at any add/drop ports with power adjusted at random by regulating SiVOA. The fundamental work principle and index test results of the new module are given.
