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...
Carbon nanotube-based fibers invented at Rice University have greater capacity to carry electrical current than copper cables of the same mass.
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...
Bragg gratings with reflectivity >93% were fabricated in Bi-Al co-doped H 2 -loaded optical fibers. Average index changes as high as +2.5×10 -3 were obtained. Positive core stress changes indicate a c...
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 ...
We experimentally assess the performance of coherent PDM-BPSK at 40Gb/s over non-zero dispersion-shifted fiber. The BPSK-based solution is found about 7.5dB more robust than the QPSK-based solution ag...
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...
