Summary

OptiFDTD enables you to design, analyze and test modern passive and nonlinear photonic components for wave propagation, scattering, reflection, diffraction, polarization and nonlinear phenomena. The core program of OptiFDTD is based on the finite-difference time-domain (FDTD) algorithm with second-order numerical accuracy and the most advanced boundary condition – uniaxial perfectly matched layer (UPML) boundary condition. The algorithm solves both electric and magnetic fields in temporal and spatial domains using the full-vector differential form of Maxwell’s coupled curl equations. This allows for arbitrary model geometries and places no restriction on the material properties of the devices. OptiFDTD dramatically improves productivity of design engineers by reducing time-to-market.

Key Features

Integrated simulation environment

OptiFDTD provides a complete and user-friendly 3D graphical user interface to enable the design, simulation and analysis of complex devices. Designs from third party CAD software can be readily imported and exported using widespread formats such as DXF and GDSII. OptiFDTD and OptiBPM can easily interoperate in order to extend the simulation range attainable by OptiFDTD alone.

 

Powerful automation and parameter sweeps

OptiFDTD designs and simulations can be fully automated using a powerful Visual Basic scripting language. The language is easy to learn and provides standard programming structures such as objects, loops, and tests. Parameter sweeps provide an easy to use graphical interface for defining parametric simulations, where one or two parameters vary at each iteration. OptiFDTD post-processing tools can take advantage of automation functionalities and assist you in optimizing your design.

 

Plane Wave Expansion band solver for photonic crystals

Fully integrated 2D PWE band solver and photonic crystal editor can help you design and simulate any type of photonic crystal problem (1D, 2D, 3D). The PWE band solver can scan through k-space following the irreducible Brillouin zone and find eigenfrequencies of your structure. Band-gaps are automatically outlined in the resulting band diagram.

 

True parallel performance

OptiFDTD takes advantage of modern 64 bit operating systems and processors. It is optimized to run efficiently on multiple cores and processors in a single machine using shared memory, providing the best possible performance and minimum memory footprint (as compared to distributed memory architectures such as MPI). For memory intensive simulations, you can use our Linux 3D simulation engine, specifically designed to take advantage of Linux computer clusters.

“We are using OptiFDTD to perform 2D and 3D
simulations of CMOS image sensor pixels to
evaluate their optical effciency. OptiFDTD is a very
versatile simulation tool and we have been very
impressed with the technical support we have
received from Optiwave.”

Advanced simulation post processing tools

OptiFDTD provides extensive simulation analysis tools. Using OptiFDTD Analyzer, you can observe time domain and frequency domain (using FFT or DFT transforms) amplitude, phase, real or imaginary values of any field component recorded by your detectors. All field data can be exported for use in third-party software tools such as Matlab™ or Origin™ for further processing or publication. Time-domain field evolution can also be visualized in the form of movies. Polarized power distribution, Poynting vectors, overlap integrals, heat absorption calculation and far-field transforms can be determined using OptiFDTD Analyzer and OptiFDTD Toolbox.
