Abstract

By eliminating redundant feedback mechanisms, we propose and experimentally validate an enhanced reservoir computing (RC)-based equalizer with simplified feedback for intensity modulation direct detection (IMDD) short-reach optical transmission systems. Experimental results demonstrate that the simplified model, which retains only the reservoir feedback loop and reduces the number of trainable parameters, achieves bit error rate (BER) performance comparable to the dual-feedback model. Without compromising equalization effectiveness, the proposed architecture reduces computational complexity and enhance scalability for practical deployment in high-speed optical networks.

基于简化反馈的IMDD传输均衡增强油藏计算

通过消除冗余反馈机制，我们提出并实验验证了一种基于增强油藏计算（RC）的均衡器，该均衡器具有简化的反馈，适用于强度调制直接检测（IMDD）短距离光传输系统。实验结果表明，简化后的模型只保留了储层反馈回路，减少了可训练参数的数量，实现了与双反馈模型相当的误码率性能。在不影响均衡效果的前提下，该架构降低了计算复杂度，增强了高速光网络实际部署的可扩展性。

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.
