Novel Analyzing Model of Bi-Directional OTDR Measurement in a Hole-Assisted Fiber
Bi-Directional OTDR Measurement Fiber Hole-Assisted
2015/5/18
A novel analyzing model of bi-direction OTDR measurement in a hole-assisted fiber (HAF) is proposed. Using this model, both information on the air-hole structure and air-hole surface roughness in a HA...
Dynamic Birefringence Induced Extensional Stress in Curled Hole-Assisted Fiber
Fiber measurements Birefringence
2015/6/10
This paper describes the dynamic birefringence induced by the extension of a curled optical hole-assisted fiber, which increases linearly under high tension. This technique can be a used for monitorin...
New propagation mode of fiber fuse with a long-period damage track in hole-assisted fiber (HAF)
Fiber characterization Microstructured fibers
2015/6/5
We observed a new fiber fuse propagation mode in HAF with an approximately 30 times larger period than that in SMF. We made the first observation of a new fiber fuse threshold power (upper threshold).

Fiber Fuse Characteristics Hole-Assisted Fiber High Power Optical Transmission Systems
2015/7/16
We evaluate fiber fuse characteristics of bend-insensitive optical fibers and show that hole-assisted fiber(HAF) is applicable as fiber fuse stopper in high-power optical transmission systems. We also...
A Hole-Assisted Fiber for Wideband Transmission from 1.0 μm to 1.6 μm
Hole-Assisted Fiber Wideband Transmission
2015/7/16
A novel hole-assisted fiber with single-mode propagation down to 1.0 μ m and relatively low macro-bending loss up to L band is fabricated. The fiber also has low loss and large effective area properti...
Ultra Low Nonlinear Telecom Fibre by Hole Assisted Technique
Nonlinear Telecom Fibre Hole Assisted Technique
2015/7/16
Hole assisted fibre with less than half nonlinearity of standard SMFs was investigated. Fabricated fibre has Aeff of 180μm 2 , reduced n2 and larger dispersion coefficient, simultaneously. Low loss sp...
Fiber fuse phenomenon in hole-assisted fibers(HAFs) was investigated. Fiber fuse propagation can be stopped as designing suitable position of air holes in HAF.
通过改变包层中空气孔的参数,孔助光纤（hole-assisted lightguide fiber）具有比传统光纤更容易调节的色散和双折射特性.采用有限差分法研究了包层空气孔数目、大小和位置等参数对孔助光纤色散和双折射特性的影响.数值计算结果表明：增加空气孔的数目和尺寸以及减小空气孔到纤芯的距离都能够使得零色散向短波长方向移动,减小空气孔与纤芯的距离有助于获得更大的双折射.
