Nonlinear finite-difference time-domain modeling of linear and nonlinear corrugated waveguides
A multidimensional, nonlinear finite-difference time-domain (NL-FDTD) simulator, which is constructed from a self-consistent solution of the full-wave vector Maxwell equations and dispersive (Lorentz), nonlinear (finitetime-response Raman and instantaneous Kerr) materials models, is used to study finite-length, corrugated, optical waveguide output couplers and beam steerers. Multiple-cycle, ult...
متن کاملCAPHE: Time-domain and Frequency-domain Modeling of Nonlinear Optical Components
We present a tool for the modeling of optical circuits, both in the frequency and in the time domain. The tool is based on the definition of a node, which can have both an instantaneous input-output relation, as well as different state variables (e.g. temperature and carrier density) and differential equations for these states. Furthermore, each node has access to part of its input history, all...
متن کاملBand Structures for 2D Photonic Crystals in Presence of Nonlinear Kerr Effect Calculated by Use of Nonlinear Finite Difference Time Domain (NFDTD) Method
We report the simulation results for impact of nonlinear Kerr effect on band structures of a two dimensional photonic crystal (2D-PhC) with no defect, a PhC based W1-waveguide (W1W), and also Coupled-Cavity Waveguides (CCWs). All PhC structres are assumed to a square lattice of constant a made of GaAs rods of radius r=0.2a, in an air background. The numerical simulation was performed using...
متن کاملTime - Domain Measurements and Modeling of Uxo
A commercial finite-element engineering-analysis code was used to model pulsed-induction (time-domain) sensing of UXO for comparison with measurements made with the Geonics EM61-3D. Late-time decay constants are observed to be independent of shape and orientation in solid nonpermeable (aluminum) objects with the same volume, in agreement with theory, except for flattened objects on end with res...
متن کاملTime Domain Modeling of Lossy Interconnects
A new model for dielectric loss, suitable for time domain modeling of printed circuit boards, is proposed. The model is based on a physical relaxation model. Complete time domain modeling of skin effect and dielectric losses in FR-4 boards are demonstrated and experimentally verified. Finally, the developed model is used to predict that FR-4 boards are useful for data rates up to 10 Gb/s.
