As the dimensions change in y, the position of the center line of the fiber in 3D space is mainained. With 3D fber profles, the width of the 2D waveguide in the x-z plane is also applied to the height, in order to model fber tapering. Channel waveguides can be tapered linearly, and fbers can be tapered linearly and proportionately. Waveguides can now be tapered in thickness in addition to width.
Easily create the most complex design without manual graphical user interface operations.Create custom libraries of scripts that represent particular components, which can be added to any new layout design.Quickly and easily convert any layout design or its parts into the script.Completely integrated with the graphical user interface, the fexible scripting tools allow for a streamlined automation process:
Editing features have also been improved, including user-defned shape creation and structure rotation.Ī powerful feature empowers users with full simulation engine automation through Visual Basic scripting. Included with Optiwave’s FDTD is a robust photonic crystal editor allowing users to edit any lattice structure and periodic layout with a number of template shapes (i.e. The periodic boundary condition, Perfect Electric Conductor (PEC) and Perfect Magnetic Conductor (PMC) boundary conditions can be used with UPML to realize more advanced simulations for periodic and symmetric layouts. Using the Uniaxial Perfectly Matched Layer (UPML) method to calculate the absorbing boundary condition in comparison with conventional PML. Optiwave’s FDTD includes an advanced boundary condition simulation feature which optimizes memory usage and provides more accurate results. 2nd-Order and 3rd-Order nonlinear materialsįDTD – Most extensive selection of excitation sources, including:.Lorentz-Drude materials – Noble metals and surface plasma materials.Multiple resonance dispersive materials.A practical application when analyzing combined signals from multiple input planes.įDTD – Most extensive material choices, including: The advanced heating absorption module in Optiwave’s FDTD supports calculations of the heating field distribution and heating absorption rate estimation.Įnables users to select the initial phase offset of a launched input wave. Metallic and lossy materials in semiconductor devices or solar cells absorb part of the wave energy and convert it to heat. Ideal for Radar Cross Section (RCS) analysis and grating simulations. A 32-bit system can only handle a maximum of 4 GB of RAM, severely limiting the amount of accessible memory in an existing system.Īrbitrary tilting plane wave excitation algorithm that separates total field and scattering field.
64-bit operating systems can utilize 16 TB (Terabytes) of RAM. As engineers tackle larger, more complex real-world problems in their designs, suffcient memory becomes crucial. With the 64-bit features of Optiwave’s FDTD, users can design and run a new generation of 64-bit simulations that address up to four billion times as much memory as 32-bit applications.
Finite-Difference Time-Domain (FDTD) is a powerful, highly integrated and user-friendly software application that enables the computer-aided design and simulation of advanced passive and non-linear photonic components.
