【摘要】：目前,密集波分复用(Dense wavelength division multiplexing,DWDM)光通信器件正朝着集成化、简易化、智能化、小型化、高速化的方向发展。作为DWDM系统的关键器件,可重构光分插复用器(Reconfigurable optical add/drop multiplexer,ROADM),是近年来的研究热点,但是目前的ROADM器件调谐速率不够快,集成度不高,真正实际应用的高速集成化的ROADM器件并不多。因此,本文研究了法布里-珀罗(Fabry-Perot,FP)谐振腔原理的ROADM器件的关键技术:(1)建立了FP谐振腔为基础的可调谐FP阵列ROADM的模型,包括:建立了FP器件的多层介质反射膜的模型,并对其反射特性做了理论计算;建立了以FP器件为基础的可调谐FP阵列ROADM模型,研究了FP-ROADM器件的关键性能参数,并对相关参数做了计算;对FP的可调谐性机制进行了理论建模,讨论了调控FP谐振腔的机制;(2)研究了FP-ROADM器件的关键技术,包括:通过数值计算方法研究了FP腔的主要性能,研究了FP-ROADM器件的主要性能,研究了有限数量的多光束干涉对FP透过率的影响,研究了FP器件可能的缺陷因素对FP性能造成的影响,研究了缺陷因素对FP-ROADM的主要参数影响。(3)通过FP腔的腔长和透过率的实验研究,推论了可调谐FP-ROADM的动态响应性能。(4)提出一种集成波分复用器的设计方案,设计了基于电致折射率可调谐的FP阵列实现ROADM的方案。设计了基于硅基芯片的多波长、多通道、多端口的FP阵列架构;研究了基于硅基芯片可调谐FP阵列的宽自由光谱范围、窄带宽、低插入损耗等参数,解决了ROADM技术在插入损耗、响应时间、大规模集成等关键问题;优化了可调谐FP阵列ROADM器件,提高了ROADM器件的性能,研究了FP-ROADM器件的大规模集成方案。设计了模拟实验,该模拟实验的ROADM器件信道数为8、信道间隔为100GHz、物理端口为16个波长通道,实现了任意波长的上传、下载及直通功能。本文所设计的可调谐FP原理的多路可重构光分插复用器方案可以灵活分配及交换不同波长信号,其主要特点是响应速度快,结构简单,把合波器、分波器和光开关等集成一起,易于集成化,易于器件大规模集成。本文的研究内容将为相关可重构光分插复用器件在实际工程中的实际应用提供了理论基础。
[Abstract]:At present, dense wavelength Division Multiplexing (DWDM) wavelength wavelength division Multiplexing (DWDM) optical communication devices are developing towards integration, simplicity, intelligence, miniaturization and high speed. Reconfigurable optical add/drop multiplicity is a hot research topic in recent years, but the tuning rate of ROADM devices is not fast enough, and the integration level is not high. Therefore, there are not many high speed integrated ROADM devices in real application. In this paper, the key technology of Fabry-Perot Fabry-Perot Fabry-Perot cavity (ROADM) resonator principle for Fabry-Perot resonator is studied. The model of tunable FP array ROADM based on FP resonator is established, including the model of multilayer dielectric reflection film of FP device. The reflection characteristics are calculated theoretically, the tunable FP array ROADM model based on FP device is established, the key performance parameters of FP-ROADM device are studied, and the relevant parameters are calculated, and the tunability mechanism of FP is theoretically modeled. The key technologies of FP-ROADM devices are discussed, including: the main properties of FP resonators and the main properties of FP-ROADM devices are studied by numerical calculation. The influence of finite number of multi-beam interference on FP transmittance and the influence of possible defect factors on FP performance are studied. The influence of defect factors on the main parameters of FP-ROADM is studied. (3) through the experimental study of cavity length and transmittance of FP cavity, the dynamic response performance of tunable FP-ROADM is inferred. (4) A design scheme of integrated wavelength division multiplexer is proposed. The scheme of realizing ROADM based on FP array with tunable refractive index is designed. The multi-wavelength, multi-channel, multi-port FP array architecture based on silicon chip is designed, and the wide spectrum range of tunable FP array based on silicon chip is studied. The parameters of narrow bandwidth and low insertion loss solve the key problems such as insertion loss, response time and large-scale integration of ROADM technology, optimize the tunable FP array ROADM devices, and improve the performance of ROADM devices. The large scale integration scheme of FP-ROADM device is studied, and the simulation experiment is designed. The channel number of ROADM device is 8, the channel interval is 100GHz, the physical port is 16 wavelength channels, and the upload of arbitrary wavelength is realized. The multichannel reconfigurable optical add / drop multiplexer based on the tunable FP principle can flexibly distribute and exchange different wavelength signals. The main characteristics of this scheme are fast response, simple structure, and combined wave synthesizer. The integration of wavelength divider and optical switch is easy to integrate and easy to integrate on a large scale. The research content of this paper will provide a theoretical basis for the practical application of related reconfigurable optical add and drop multiplexing devices in practical engineering.
