摘要
针对底层短距传输系统的升级革新面临器件带宽、成本、功耗等多重受限因素,基于直接探测技术,探索光偏振维度空间的复用,在低成本条件下实现短距离光互连传输速率的倍增.在统一的斯托克斯向量空间中对3种光偏振复用直检系统进行了理论建模分析,给出了3种系统性能优劣势的理论成因,并在参数统一的仿真验证平台上,对3种不同的系统方案进行了详细的分析比较.
The communications and processing of big data brings great pressure to the short reach optical systems because of its ever-increasing requirement on transmission rate.However, the upgrade of transmission systems faced many factors in cost, speed, and distance.Polarization division multiplexing combined with direct detection (PDM-DD) is a promising way to significantly improve the transmission rate of short reach systems.Three popular PDM-DD approaches were analyzed in Stokes vector space theoretically, in which, their performance are investigated by simulation with uniform model parameters.
