VPIdeviceDesigner™ is a versatile simulation framework for the analysis and optimization of integrated photonic devices, waveguides, and optical fibers.

This powerful design tool offers a set of full-vectorial, semi-vectorial, and scalar finite-difference mode solvers for waveguide and fiber analysis as well as a beam propagation method (BPM) and an eigenmode expansion method (EME) for simulating 2D and 3D photonic devices.

VPIdeviceDesigner supports the flexible definition of 2D waveguide and fiber cross-sections and 3D device layouts with realistic (dispersive, temperature-dependent, etc.) optical materials, widely customizable nonuniform meshing, and perfectly matched layers.

It enables comprehensive analysis of simulation results – including manipulation of the calculated electromagnetic fields – and facilitates easy design automation based on any desired performance criteria.

VPIdeviceDesigner provides a user-friendly object-oriented Python interface integrated with open-source libraries for mathematics, science, and engineering, including the libraries NumPy, SciPy, and the comprehensive 2D plotting library Matplotlib.
It also enables easy creation of compact simulation models for waveguides and devices, integrating seamlessly with VPIcomponentMaker Photonic Circuits and VPItoolkit PDK <fab> extensions for PIC simulations.
