Abstract

This work reports higher order LP11 modes in ultrafast mode-locked fiber laser at the O-band regime. The mode-locking was achieved by using bismuth telluride (Bi2Te3) as an optical modulator in a praseodymium-doped fluoride fiber (PDFF) laser which operates at 1300.5 nm. Bi2Te3 was prepared by liquid phase exfoliation (LPE) process and then it was drop-casted onto the arc-shaped fiber, which behaves as an optical modulator. The mode-locking was obtained within the pump power range of 106.8 to 133.2 mW. The pulse repetition rate was at 0.407 MHz with a signal-to-noise ratio (SNR) of 53.4 dB. The ultrafast pulses of 890 fs duration with a pulse energy of 2.4 nJ were achieved. At the output, by using the offset splice spot (OSS) technique the higher-order modes were excited in the two-mode fiber (TMF). These higher-order modes were LP11 modes with a two-lobe structure visualized using the Thorlabs beam profiler.

以碲化铋为光调制器的1.3 μm LP11模全光纤超快激光器

本文报道了o波段超快锁模光纤激光器中的高阶LP11模式。采用碲化铋（Bi2Te3）作为光调制器，在1300.5 nm的掺镨氟光纤（PDFF）激光器中实现了锁模。采用液相剥离（LPE）法制备Bi2Te3，并将其滴铸到弧形光纤上，作为光调制器。在106.8 ~ 133.2 mW的泵功率范围内实现锁模。脉冲重复频率为0.407 MHz，信噪比（SNR）为53.4 dB。获得了持续时间为890 fs、脉冲能量为2.4 nJ的超快脉冲。在输出端，利用偏置拼接点（OSS）技术在双模光纤（TMF）中激发高阶模式。这些高阶模式是LP11模式，具有双瓣结构，使用Thorlabs光束剖面仪可视化。

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
