The NLO properties include the electro-optic effect (EOE) and the third-order nonlinear optical susceptibility (TONOS) whereas the other two related properties being total optical dielectric function (TODF) and the intraband

Photocarrier relaxation and saturable absorption in defect-rich, direct chemical vapor deposition-grown graphene glass J. Nonlinear Opt. Phys. Mater. (IF 2.7) Pub Date : 2023-07-26 Xin Zhao, Fang Liu, Xu-Dong Chen, Zhi-Bo Liu, Xiao-Qing Yan, Jian-Guo Tian
Direct growth of large-area uniform graphene films on insulating materials could facilitate the applications of graphene in optoelectronic devices. The ultrafast photocarrier relaxation and saturable absorption of direct chemical vapor deposition-grown graphene glasses, with lots of defects, are studied by using femtosecond time-resolved pump–probe and Z-scan techniques at 800 nm. We find that both

In this study, we report photonic band structures and optical transmissions of some SiC polytypes, such as 3C, 2H, 4H, and 6H, and their multilayers, which have the form of a hexagonal photonic crystal at two-dimensional (2D) scale. Through the finite-difference time-domain computational simulations, we found that spatial electric-field variations of electromagnetic waves depend on the radius of dielectric

Diverse optical solitons to the Radhakrishnan–Kundu– Lakshmanan equation for the light pulses J. Nonlinear Opt. Phys. Mater. (IF 2.7) Pub Date : 2023-07-24 Kang-Jia Wang, Guo-Dong Wang, Feng Shi
In this paper, we study the Radhakrishnan–Kundu–Lakshmanan equation (RKLE) that plays a key role in modeling the nonlinear propagation of the light pulses. Two novel methods namely Wang’s Bäcklund transformation-based method and Wang’s direct mapping method are employed to construct the diverse exact optical soliton solutions. Abundant exact solutions like the bright soliton solution, dark soliton

The modulation of electrostatic potential and optoelectronic characteristics of Janus MoSSe/MX2 (M = Mo, X = S, Se) van der Waals (vdW) heterostructures with strain engineering were studied by first principles. Based on the effection of uniaxial strain, the electronic properties of heterostructures not only are induced to form direct band gap and indirect band gap and even semiconductor-metal transformation

Reflection and transmission of both continuous and solitary waves in conductive media with Kerr-type nonlinearity J. Nonlinear Opt. Phys. Mater. (IF 2.7) Pub Date : 2023-05-27 Luis A. Manzaneda, Deterlino Urzagasti
We present a theoretical study of the incidence of nonuniform waves between two dissipative media with finite conductivity and with a nonlinear response to the applied electric field, which is associated with the Kerr effect. From the Adler–Chu–Fano formulation, the complex propagation vectors, transmitted and reflected angles, and Fresnel coefficients are obtained for the two linear polarization states

A novel plasmonic waveguide structure consisting of a rectangular resonator side coupled with a split ring resonator (SRR) and a metal–insulator–metal (MIM) waveguide with metal baffle was proposed. The transmission characteristics of the present structure were simulated by a finite-difference time-domain (FDTD) method. The results show that the structure can realize three typical plasmonically-induced
