Abstract

A single- and dual-wavelength switchable fiber laser based on composite interference filtering is proposed and experimentally demonstrated. By utilizing a seven-core fiber interferometer cascaded with a Sagnac loop, the linewidth of the laser output is narrowed to less than 0.02 nm, and the optical signal-to-noise ratio better than 61 dB. The laser output wavelengths can be switched between single- and dual-wavelength by adjusting the polarization controller and the pump power. The laser exhibits high stability in both wavelength and power. The proposed laser structure is simple, with high OSNR and excellent stability, making it promising for applications in optical communication, sensing, and wavelength division multiplexing systems.

基于复合干涉滤波的单/双波长可切换光纤激光器

提出了一种基于复合干涉滤波的单、双波长可切换光纤激光器，并进行了实验验证。利用Sagnac环级联的七芯光纤干涉仪，激光输出线宽可缩小至0.02 nm以内，光信噪比优于61 dB。通过调节偏振控制器和泵浦功率，激光输出波长可以在单波长和双波长之间切换。该激光器在波长和功率上都具有很高的稳定性。该激光器结构简单，具有高OSNR和优异的稳定性，在光通信、传感和波分复用系统中具有广阔的应用前景。
