在二极管泵浦的拉曼光纤激光器的多模渐变折射率光纤中,通过飞秒脉冲刻写FBG,可产生接近衍射极限的输出光束。这一技术已经应用于工业(通信、生物医学、材料加工、基础设施和能源行业)中的各种激光和传感器系统。从超长光纤自然瑞利散射引起的随机拉曼激光的发现出发,主讲人将介绍使用fs脉冲刻写具有规则/随机的3D折射率结构的多模、多芯光纤的技术,以及新型光纤所具有的独特激光和传感性能,这种新型光纤有望在物理上...
Soliton fusion is a fascinating and delicate phenomenon that manifests itself in optical fibers in case of interaction between co-propagating solitons with small temporal and wavelengths separation. T...
We report a comparative experimental study of the attenuation spectra transformations for a series of Yb doped alumino-germano silicate fibers with different contents of Yb3+ dopants, which arise as t...
The fabrication of few-mode Cr-doped double-clad crystalline fiber (FMCDCF) using a multiple core tuning process is demonstrated for the first time. The FMCDCF exhibited a core diameter of 2 ± 0.6 μm ...
The fabrication of Cr-doped fibers (CDFs) using fiber drawing-tower combined with non-silica powder-in-tube (PIT) technique to achieve the active application of chromium ions in fiber is demonstrated ...
High data rate telecommunication networks operating at 100 Gb/s require low loss fibers with very large effective areas to mitigate nonlinearities. The state of the art fiber technologies needed to ac...
A new functionality of air-holes, worked as prevention for micro-deformation induced loss without affecting other properties, is demonstrated. A fiber with Aeff of 150μm 2 was fabricated by utilizing ...
Excitation-emission properties of Bi:SiO 2 optical fibers (without other dopants) were investigated in the wavelength region 400-1600nm. Laser generation in fibers of such composition was demonstrated...
We present a comprehensive study that explains the specific mechanisms that govern the cutoff behaviors of G.657 single-trench-assisted Bend-Insensitive Single Mode Fibers (BI-SMFs) compared to those ...
The nonlinear propagation characteristics in a hydrogenated amorphous silicon core optical fiber are investigated to demonstrate ultra-fast all-optical switching by cross-absorption modulation.
We overview Rayleigh, Brillouin and Raman scattering in optical fibers, fiber amplifiers and lasers focusing on their mutual cooperation dynamics and explaining associated effects such as multi-cascad...
The quantization of the light field is important for understanding some aspects of optical fiber systems: the quantum limit of amplifiers, the dynamics of solitons below shot noise and the appearance ...
A new bandwidth measurement method for multimode fibers is developed through measuring bit error rate and power penalty associated with the testing system. Experimental calibration procedure and actua...
We describe an OFDR-based procedure to measure the spin of optical fibers with spin rates exceeding OFDR resolution. Fibers are twisted to locally unwind the spin and measurements are afterward reasse...
An ongoing problem in any network finds craft personnel opening incorrect optical circuits for diagnosis. We demonstrate an instrument that non-intrusively induces a time-varying loss on optical fiber...
