Abstract:
This paper details the design of a 1 × 8 optical power divider, using a gallium nitride (GaN) semiconductor on sapphire, which can be applied to underwater optical wireless communication. The design consists of nine parallel rectangular waveguides which are based on mode coupling phenomena. Analysis of the design was performed using the beam propagation method (BPM). The optimization was conducted using the 3D finite difference (FD)-BPM method with an optical signal input at the wavelength required for maritime application of λ = 0.45 µm. The signal was injected into the central waveguide. The

Abstract:
Optical logic gates for OR-AND-NOT, NOR and exclusive-XNOR operations in waveguides consisting of nonlinear material are numerically investigated by means of FD-BPM (Finite Difference Beam Propagation Method). The proposed devices are designed utilizing the self-routing characteristics of nonlinear X-crossing and Y-branching structures when they are operated with one input beam or two. The numerical simulations show that the proposed structures can favorably be applied to optical data processing and computing as fundamental logic gates.

Abstract:
SOI Ridge nanowire waveguide (RNW) has advantages of strong confinement of optical mode, low propagation loss, small bend radius and fully compatible with CMOS technique, etc. An ultra-compact Y-branch coupler based on SOI RNW was designed and fabricated. Based on the finite-difference beam propagation method (FD-BPM), key parameters of the coupler were analyzed. Then the device was fabricated by electron beam lithography (EBL) and inductively coupled plasma (ICP) reactive ion etching. Results showed that the propagation loss of RNW was 1.89 dB/mm, and the radiation loss of the coupler with br

Abstract:
A novel finite element method (FEM) based wide-angle (WA) beam propagation method (BPM) was presented whereby the scalar Helmholtz equation was solved without using the slow varying envelope approximation (SVEA) and was more general and precise than the previous well-known WA-BPM proposed by Hadley. The accuracy of this novel scheme was demonstrated in comparison with the existing approach.

Abstract:
The near-field characteristics of a radially-variant vector beam (RVVB) are analyzed by using the vectorial angular spectrum method. The non-paraxial RVVB can be decomposed into the propagating wave and the evanescent wave in near field. The coherent superposition of the longitudinal and transverse components of the RVVB results in a three-dimensional (3D) profile of the spin angular momentum flux density (SAM-FD). The evanescent wave part dominates the near field of a highly non-paraxial RVVB. The longitudinal component has a large impact on the 3D shape of the optical SAM-FD. Therefore, the

Abstract:
We adapted a fast Fourier transform-based Beam Propagation Method (FFT-BPM) to investigate waveguide discontinuities in plasmonic waveguides. The adaptation of the FFT-BPM to treat transverse magnetic (TM) fields requires the circumvention of two major difficulties: the mixed derivatives of the magnetic field and waveguide refractive index profile in the TM wave equation and the step-like index change at the transverse metal-dielectric boundary of the plasmonic guide and the transverse boundaries of the dielectric waveguide as well. An equivalent-index method is adopted to transform TM fields

Abstract:
In this paper, we are investigating the potential and limits of a meshless Lagrangian technique, called Smoothed Particle Hydrodynamics (SPH), as a method for acoustic simulations. Currently the most common techniques for acoustic simulations draw on mesh-based methods such as the Boundary Element Method (BEM), Finite Differences Method (FD) and Finite Element Method (FEM). Though many improvements have been made to each class of methods during the last few years, they still have their weaknesses. Difficulties arise as soon as inhomogeneous media, moving boundaries or aeroacoustic effects are
