Based on the nonlinear coupled wave equations, the nonreciprocal response of the third-harmonic generation process has been theoretically investigated in nonlinear photonic crystals with a defect embedded. The simulation results have shown that compl

An index profile renormalization method is proposed to study the effective refraction index increase in a high-index contrast waveguide bend such as a silicon waveguide bend. This method transforms a waveguide bend to an equivalent straight waveguide

The Laguerre-Gaussian (LG) beam demonstrates great potential for optical communication due to its orthogonality between different eigenstates, and has gained increased research interest in recent years. Here, we propose a dual-output mode analysis me

Abstract The nonreciprocal response of the SHG process in 1D periodical nonlinear photonic crystals with a defect embedded has been theoretically studied by solving the nonlinear coupled equations. The nonreciprocal response has been deduced analytic

The atmospheric turbulence disturbs the phase fronts of orbital angular momentum (OAM) beams, which significantly affects the detection of beam modes. In this paper, we propose a method based on the convolutional neural network (CNN) to detect OAM mo

A flexible phase-matching method is introduced to manipulate the energy flow in nonlinear frequency conversion processes. With the use of photonic crystal as the reflective medium, the phase mismatching could be adjusted by the interface and the nonl
