摘要

本文采用一种简单的功率耦合方法，提出了一种可切换波长布里渊拉曼光纤激光器（BRFL）的新结构。在实验中测试了不同的功率耦合比，并确定了50/50耦合器和80/20耦合器的组合是实现最佳可切换波长间隔的最有效方法。当拉曼泵浦功率超过1550 mW时，连续观察到单个布里渊波长间隔。单行距（SS）和双行距（DS）下，BRFL最大株系为441株和213株。此外，系统表现出显著的平整度，其中SS达到了6 dB平整度，DS达到了令人印象深刻的1.6 dB平整度。这些结果强调了所提出的功率耦合方法的有效性，为可切换的多波长BRFL系统提供了简单而强大的解决方案。

Optimized power coupling for enhanced wavelength switching in Brillouin-Raman fiber lasers

In this paper, we propose a new configuration of switchable wavelength Brillouin Raman Fiber Laser (BRFL) using a simple approach of power coupling. Various power coupling ratios were tested during the experiment, and the combination of a 50/50 coupler and an 80/20 coupler was identified as the most effective for achieving optimal switchable wavelength spacing. When the Raman pump power exceeded 1550 mW, a single Brillouin wavelength spacing was consistently observed. The BRFL achieved a maximum of 441 lines at single spacing (SS) and 213 lines at double spacing (DS). Additionally, the system exhibited remarkable flatness, with the SS achieving a 6 dB flatness and the DS achieving an impressive 1.6 dB flatness. These results underscore the effectiveness of the proposed power coupling method, offering a simple yet powerful solution for switchable multiwavelength BRFL systems.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
