ABSTRACT We experimentally present the first reported integrated cross-modulated forward Raman pump, with low-cost, power-efficient VCSELs. A single-mode VCSEL is directly modulated with 8.5 Gbps data and transmitted over a 50.7 km SMF-Reach fibre. Exploiting the 6.9 dB flat-gain of a forward Raman pump, an error-free transmission is experimentally achieved. Network efficiency is maximized by modulating the forward Raman pump with 8.5 Gbps data and transferred over the fibre link. To the best of our knowledge, it is the first time a forward Raman pump is utilized for simultaneous data amplification and transmission. Inherent VCSEL frequency chirping leads to an error-flow over a 50.7 km fibre link. With unmodulated forward Raman pump, a transmission penalty of 0.83 dB is incurred. However, modulated forward Raman pump results in a crosstalk penalty of 0.47 dB over the transmission link. This work offers a novel enabling technique for simultaneous network capacity, efficiency and reach optimization for next-generation optical interconnects.

具有 8.5 Gbps 数据调制前向拉曼泵信号的集成扩展范围 VCSEL 互连

摘要 我们实验性地展示了第一个报告的集成交叉调制前向拉曼泵，具有低成本、高能效的 VCSEL。单模 VCSEL 直接用 8.5 Gbps 数据调制并通过 50.7 公里 SMF-Reach 光纤传输。利用前向拉曼泵的 6.9 dB 平坦增益，通过实验实现了无差错传输。通过使用 8.5 Gbps 数据调制前向拉曼泵并通过光纤链路传输，可以最大限度地提高网络效率。据我们所知，这是第一次使用正向拉曼泵同时进行数据放大和传输。固有的 VCSEL 频率啁啾导致 50.7 公里光纤链路上的错误流。对于未调制的前向拉曼泵，会产生 0.83 dB 的传输损失。然而，调制前向拉曼泵会导致传输链路上的串扰损失为 0.47 dB。这项工作为下一代光互连的同步网络容量、效率和范围优化提供了一种新颖的使能技术。
