Journal ArticleDOI
Numerical analysis for structure optimization of seven-core photonic crystal fibers
TL;DR: In this article, the eigenvalue equation associated with seven-core photonic crystal fiber was derived from coupled-mode equation, and the relationship between fiber structure and coupling coefficient was fully discussed through changing the wavelength, hole pitch and core distance.
Journal ArticleDOI
Experimental analysis of the dependence factor duringsupercontinuum generation in photonic crystal fiber
TL;DR: An experimental study of supercontinuum generation in a photonic crystal fiber with zero dispersion wavelength 780?nm by femtosecond laser and its dependence factor is presented in this article.
Journal ArticleDOI
Photo-induced insulator-metal transition of silicon-based VO 2 nanofilm by THz time domain spectroscopy
Wang Chang-Lei,Tian Zhen,Xing Qi-Rong,Gu Jianqiang,Liu Feng,Hu Ming-Lie,Chai Lu,Wang Qing-Yue +7 more
TL;DR: In this article, the photo-induced insulator-metal transition for silicon-based VO 2 nanofilm is studied by THz time-domain spectroscopy (THz-TDS).
Journal ArticleDOI
A mode-locked Yb 3+ -doped double-clad large-mode-area fiber laser
TL;DR: In this paper, a compact and highly stable high pulse energy passively mode-locked fiber laser is presented, where a segment of Yb 3+ -doped double-clad large-mode-area fiber with extremely low nonlinearity is developed as the active medium.
Journal ArticleDOI
Simulation of Femtosecond Pulse Propagation through Hollow Fibre Filled with Noble Gases of Gradient Temperature
Song Zhen-Ming,Zhang Guang-Xiao,Cao Shi-Ying,Pang Dong-Qing,Chai Lu,Wang Qing-Yue,Zhang Zhi-Gang,Zhang Zhi-Gang +7 more
TL;DR: In this paper, a novel technique for generating intense few to mono-cycle femtosecond pulses was proposed, where the spectrum of the output pulses was increased by 67% and the transform limited pulse width was reduced almost by half compared with those obtained with hollow fibres in uniform temperature.
