We present an optical modeling approach for calculating vertical-cavity surface emitting laser (VCSELs) modes based on the bidirectional beam propagation method. Compared with existing approaches, it is flexible, efficient, and convenient. To demonst

We propose a modification of the procedure for deriving continuum equations from kinetic theory. Though we start in the customary way from an expansion in mean free path, we do not apply solvability conditions in each order, as is usually done. Thus

When the alternating direction implicit-finite difference time domain method (ADI-FDTD) is applied to simulating photonic devices, full efficiency can not be achieved if reasonable accuracy is to be kept, due to numerical errors such as numerical dis

In this letter, we have designed and fabricated low-loss ultrasmall corner mirrors and T-branches on thin silicon-on-insulator material system. The measured performance of the devices agrees with simulations using finite-difference time-domain calcul

A novel approach to the bidirectional beam propagation method, which can treat multiple dielectric interfaces, is developed and implemented using iterative methods. Comparisons with two previously published results demonstrate its accuracy, as well a

This study demonstrates a new approach based on the finite-difference time-domain (FDTD) method that transcends the described modeling limitations. This approach can be used to determine both the sub-wavelength spatial features of the optical field,

An approach based on the finite-difference time-domain method is developed for simulating the dynamics of passive mode locking in vertical-cavity surface-emitting lasers (VCSELs). The material response is modeled by the effective semiconductor Bloch

We demonstrate the calculation of loss in microstructured optical fibers using the finite-difference time-domain algorithm. The method uses direct modal propagation with longitudinal periodic boundary conditions. We compare the results to existing me

The existence and dynamics of one-dimensional spatial solitons formed upon propagation in quasiphase-matched gratings, through three-wave parametric interaction, is analyzed. We study the general case in which the grating exhibits a periodic modulati
