摘要

为了实现远距离传输的模分复用（MDM），信号放大器的发展至关重要，如掺铒光纤放大器（EDFA）。包层泵作为EDFA的解决方案，以其低成本、高增益的特点受到了人们的关注。本文提出了一种基于双包层无源光纤（DCF）的包层泵浦耦合器（CP），该耦合器采用熔锥技术制备，支持LP01、LP11、LP21和LP02四种模式的传输。该器件的光损耗小于0.3 dB，并且不会在传输线中引入新的串扰，保证了优异的模束质量。该器件与四模掺铒光纤（EDF）融合拼接，实现了非常低的拼接损耗。基于该器件的EDFA具有出色的性能。在c波段，它可以实现大于21.56 dB的平均增益，平均差分模式增益（DMG）为1.42 dB。四模同时放大时，增益超过19.21 dB， DMG小于2.51 dB，噪声系数小于7.348 dB。这对于在模分复用系统中实现远距离信号传输具有重要意义。

A Cladding-Pumped Device for Modal Gain Equilization Based on Rippled Few Mode Fiber

To achieve mode-division multiplexing (MDM) for long-distance transmission, the development of signal amplifiers, such as erbium-doped fiber amplifiers (EDFA), is crucial. As a solution for EDFA, cladding pump has gained attention due to its low cost and high gain. This paper presents a cladding pump coupler (CP) based on double cladding passive optical fiber (DCF), fabricated using the fused taper technique, which supports the transmission of four modes: LP₀₁, LP₁₁, LP₂₁, and LP₀₂. The optical loss of this device is less than 0.3 dB, and it does not introduce new crosstalk in the transmission line, ensuring excellent mode beam quality. The fabricated device is fusion-spliced with a four-mode erbium-doped fiber (EDF), achieving very low splice loss. The EDFA based on this device exhibits outstanding performance. In the C-band, it can achieve an average gain greater than 21.56 dB, with an average differential mode gain (DMG) of 1.42 dB. When amplifying four modes simultaneously, the gain exceeds 19.21 dB, the DMG is less than 2.51 dB, and the noise figure (NF) is less than 7.348 dB. This is of great significance for enabling long-distance signal transmission in mode-division multiplexing systems.
