If you are facing the challenge of long simulation runs or concerned about the accuracy in your simulation results, or your design is just too big or complex to simulate, our unique 3D full-wave simulation approach may be the answer

Tech-X has been doing large physical simulations for over two decades. We are recognized leaders in solving large, daunting simulation tasks, where accurate results are critical. We have created simulation products based on a rich mix of physics and computer science expertise—core to achieving large simulations hosted on HPCs or Linux clusters. Read background information on our core simulation capabilities.

The Tech-X advantage is accuracy and speed. Simply stated, we have demonstrated that simulation jobs that currently take many days or weeks to deliver accurate results can be run in hours. This means that you no longer have to sacrifice accuracy for reduced run-times.  And because of that, you can afford to perform very thorough simulations on unique device structures, composed of both waveguide and free space regions. You can optimize the model, at the same time as ELIMINATING a testchip run or two.

The accuracy is achieved by using time-based, full-wave simulation based on a single 3D physical model. Echelle Grating S-parametersThe simulation uses the full fidelity of classical FDTD, combined with conformal meshing representing complex shapes and multimaterials. This single physical model describes the entire 3D geometry and wave effects in their entirety without simplifications. Tech-X uses properties provided by the foundry or other fiber materials. We simulate with material and geometric dispersion, and can capture the impact of 3D reflections. And because our work is time-based, we can analyze the entire frequency spectrum in a single run. We use frequency analysis to represent the effects of channels separation, gain and cross talk. This means that rather than solely relying on a Design-of Experiments (DoE) testchip runs, you can run multiple simulations across the likely process window 3D geometries to select the optimum center design before DoE fabrication.

The speed is achieved by implementing highly-paExample Complex Device Statisticsrallel algorithms and through our expertise of working with supercomputing resources. 

We use the finite-difference time-domain FDTD method to perform a full-wave simulation of photonic structures. Tech-X has the expertise in nanophotonic device modeling to create your photonic integrated circuit simulation and the capability to perform simulations using a grid containing billions of cells.
