[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.
