摘要

宽带模式转换器是空分复用和波分复用系统中必不可少的器件。采用全光纤器件产生三阶以上低损耗、高模式纯度的高阶模式存在很大的挑战。本文提出并制作了一种全光纤LP41模式变换器，该变换器采用锥形的九芯单模光纤束。实验结果表明，该全光纤LP41模式变换器具有低损耗、高纯度、超宽带的特点。插入损耗小于0.4 dB。奇数LP41在1310 nm处纯度为95.09%，工作带宽超过280 nm。

Low-loss, high-purity, and ultrabroadband all-fiber LP41 mode converter employing a mode-selective photonic lantern [Invited]

Broadband mode converters are essential devices for space-division and wavelength-division multiplexing systems. There are great challenges in the generation of higher-order modes above the third order with low loss and high mode purity employing all-fiber devices. In this paper, an all-fiber LP41 mode converter is proposed and fabricated by tapering a nine-core single-mode fiber bundle. Experimental results indicate that this all-fiber LP41 mode converter is low-loss, high-purity, and ultrabroadband. The insertion loss is less than 0.4 dB. The purity of odd LP41 at 1310 nm is 95.09%, and the operating bandwidth exceeds 280 nm.

期刊介绍： Chinese Optics Letters (COL) is an international journal aimed at the rapid dissemination of latest, important discoveries and inventions in all branches of optical science and technology. It is considered to be one of the most important journals in optics in China. It is collected by The Optical Society (OSA) Publishing Digital Library and also indexed by Science Citation Index (SCI), Engineering Index (EI), etc. COL is distinguished by its short review period (~30 days) and publication period (~100 days). With its debut in January 2003, COL is published monthly by Chinese Laser Press, and distributed by OSA outside of Chinese Mainland.
