3D structured Bessel beam polarization and its application to imprint chiral optical properties in silica
Jiafeng Lu, Mostafa Hassan, Francois Courvoisier +6
Polarization plays crucial role in light-matter interactions; hence its overall manipulation is an essential key to unlock the versatility of light manufacturing, especially in fem…
Generation of femtosecond optical vortex beams in all-fiber mode-locked fiber laser using mode selective coupler
Teng Wang, Feng Wang, Fan Shi +4
We experimentally demonstrated a high-order optical vortex pulsed laser based on a mode selective all-fiber fused coupler composed of a single-mode fiber (SMF) and a few-mode fiber…
Passively Q-switched EDFL using Fe3O4-nanoparticle saturable absorber
Xuekun Bai, Chengbo Mou, Luxi Xu +4
We experimentally demonstrate a passively Q-switched erbium-doped fiber laser (EDFL) operation by using a saturable absorber based on Fe3O4 nanoparticles (FONP) in magnetic fluid (…
Dispersive wave emission from dark solitons in microresonator-based Kerr frequency combs
Shaofei Wang, Xianglong Zeng
Taking advantage of an extended Lugiato--Lefever equation with third-order dispersion, we numerically show that dark cavity solitons formed in normal dispersion of microresonators…
Analysis of high-order dispersion on ultrabroadband microresonator-based frequency combs
Shaofei Wang, Hairun Guo, Xuekun Bai +1
We numerically investigate the influence of high-order dispersion on both temporal and spectral characterizations of microresonator-based optical frequency combs. The moment method…
Soliton Coupling Effect: Group-velocity-matching Dispersive Wave Generation and Spectral Tunneling
Hairun Guo, Shaofei Wang, Xianglong Zeng +1
Concept of spectral soliton coupling is proposed to explain the group-velocity-matching dispersive wave generation and the soliton spectral tunneling effect. Soliton eigen state is…
Generalized Nonlinear Wave Equation in Frequency Domain
Hairun Guo, Xianglong Zeng, Morten Bache
We interpret the forward Maxwell equation with up to third order induced polarizations and get so called nonlinear wave equation in frequency domain (NWEF), which is based on Maxwe…
Soliton compression to few-cycle pulses with a high quality factor by engineering cascaded quadratic nonlinearities
Xianglong Zeng, Hairun Guo, Binbin Zhou +1
We propose an efficient approach to improve few-cycle soliton compression with cascaded quadratic nonlinearities by using an engineered multi-section structure of the nonlinear cry…
Nonlinear Wave Equation in Frequency Domain: Accurate Modeling of Ultrafast Interaction in Anisotropic Nonlinear Media
Hairun Guo, Xianglong Zeng, Binbin Zhou +1
We interpret the purely spectral forward Maxwell equation with up to 3 order induced polarizations for pulse propagation and interactions in quadratic nonlinear crysta…
The anisotropic Kerr nonlinear refractive index of the beta-barium borate (β-BaB2O4) nonlinear crystal
Morten Bache, Hairun Guo, Binbin Zhou +1
We study the anisotropic nature of the Kerr nonlinear response in a beta-barium borate (β-BaB2O4, BBO) nonlinear crystal. The focus is on determining the relevant cubic t…
