摘要

【目的】

随着信息技术的高速发展和全球数据流量的激增，通信系统对高带宽、低时延和高可靠性的需求日益迫切，推动了信号频率向更高波段迁移。光学频率梳（OFCs）因其在高精度光谱学、光通信、量子信息处理和时间频率计量中的广泛应用而成为研究热点。相比于传统红外频梳，可见光频梳凭借其更高的带宽和更低的干扰特性，在天地一体通信和数据中心高速互联传输中展现出独特优势。然而传统红外频梳技术难以直接运用于可见光波段，因此文章研究旨在开发高效和低成本的可见光频梳生成方法，以满足未来高速光通信需求。

【方法】

文章提出了一种在可见光波段基于多频的正弦波和锯齿波混合的波形驱动相位调制器来生成频梳的方法，在波形级直接进行倍频混频处理以降低硬件需求，同时结合正弦波的平坦性和锯齿波的宽谱性以提升生成的有效频梳数量。该方法无需复杂的级联结构，设备简单、成本低且可灵活调整调制参数，为实现高性能可见光频梳提供了高效和实用的解决方案。

【结果】

实验结果表明，在532 nm波段使用该方法可以在载波光功率10 dBm变化范围内生成34条有效频梳，频梳数量约为传统正弦波驱动的3倍，光谱密度显著增强。

【结论】

文章所提方法可以低复杂性设备实现高效和平坦可见光频梳的生成，有望为未来第六代移动通信技术（6G）全光网络、数据中心互联和物联网提供高质量多载波源，具有广泛应用前景。

Abstract

【Objective】

With the rapid development of information technology and the surge in global data traffic

the demand for high bandwidth

low latency

and high reliability in communication systems is becoming increasingly urgent

driving the migration of signal frequencies to higher bands. Optical Frequency Combs (OFCs) have become a research hot topic due to their wide applications in high-precision spectroscopy

optical communications

quantum information processing

and time and frequency metrology. Compared with traditional infrared frequency combs

visible light frequency combs have unique advantages in space-to-ground communications and high-speed interconnection transmission of data centers due to their higher bandwidth and lower interference characteristics. However

traditional infrared frequency comb technology is difficult to directly apply to the visible light band. Therefore

this study aims to develop an efficient and low-cost visible light frequency comb generation method to meet the needs of future high-speed optical communications.

【Methods】

This paper proposes a method for generating frequency combs in the visible light band by driving a phase modulator using a waveform-driven multi-frequency mixture of sine and sawtooth waves. Direct frequency multiplication and mixing at the waveform level reduces hardware requirements

while combining the flatness of sine waves with the wide spectral characteristics of sawtooth waves to increase the number of effective frequency combs generated. This method eliminates the need for complex cascade structures

offers simple and low-cost equipment

and allows for flexible adjustment of modulation parameters

providing an efficient and practical solution for achieving high-performance visible light frequency combs.

【Results】

Experimental results show that using this method in the 532 nm band can generate 34 effective frequency combs within a 10 dBm carrier optical power variation

which is approximately three times the number of frequency combs used in traditional sinusoidal wave drive

and the spectral density is significantly enhanced.

【Conclusion】

This method can achieve efficient and flat visible light frequency comb generation with low-complexity equipment

which is expected to provide high-quality multi-carrier sources for future 6th Generation Mobile Communication Technology (6G) all-optical networks

data center interconnection and the Internet of Things

and has broad application prospects.
