摘要

混合泵浦方案允许在多模泵浦光放大器的核心之间存在光纤损耗变化和核心相关增益的情况下，在基于多核心光纤的传输系统的核心之间均衡传输性能。分布式拉曼放大的功率均衡改善了噪声特性，但由于串扰增加，导致信噪比降低。在实验装置中，用这种方法补偿50km长的沟槽辅助7芯光纤的外芯损耗，结果表明，中心芯的OSNR损失增加了约30%。

Impact of Inter-Core Loss and Gain Equalization on Transmission Performance in Multi-Core Systems

Hybrid pumping schemes allow for equalizing transmission performance across the cores of a multi-core fiber based transmission system in the presence of fiber loss variations between the cores and core-dependent gain of the involved multi-mode pumped optical amplifiers. Power equalization by distributed Raman amplification comes with improved noise characteristics, but leads to reduced signal-to-interference ratio due to increased crosstalk. In an experimental setup, compensating loss in the outer cores of a 50km long trench-assisted 7-core fiber with this approach is shown to lead to an OSNR penalty increase by around 30% in the center core.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
