Single-mode helical Bragg grating waveguide created in a multimode coreless fiber by femtosecond las
[期刊论文] 作者：JunHe,JiaHe,XizhenXu,BinDu,BaijieXu,ChangruiLiao,ZhiyongBai,YipingWang,
来源：PhotonicsResearch 年份：2021
We demonstrate the fabrication of single-mode helical Bragg grating waveguides (HBGWs) in a multimode coreless fiber by using a femtosecond laser direct writing technique. This approach provides a single-step method for creating Bragg grati......

Post-Treatment Techniques for Enhancing Mode-Coupling in Long Period Fiber Gratings Induced by CO2 L
[期刊论文] 作者：XizhenXU,JianTANG,JingZHAO,KaimingYANG,CailingFU,QiaoWANG,ShenLIU,ChangruiLIAO,JiarongLIAN,YipingWANG,
来源：PhotonicSensors 年份：2015
Two promising post-treatment techniques, i.e. applying tensile strain and rising temperature, are demonstrated to enhance the mode-coupling efficiency of the CO2-laser-induced long period fiber gratings (LPFGs) with periodic grooves. Such t......
