High-Performance Photonic Simulation

Stop simulating what fits

Simulate what matters

WaveSim Pro is a photonic simulation platform for high-speed, high-accuracy electromagnetic analysis of complex optical designs. Available as both a cloud-hosted web application and an on-premises deployment, it integrates advanced numerical methods with GPU-accelerated computing to deliver scalable, high-performance simulations.

The web-based platform enables simulations to run directly in the browser without requiring local hardware or software installation.

MBS OVER FDTD

Simulate what matters, not just what fits

Photonic and micro-optical design is increasingly limited not by the engineer's question, but by what the solver can hold in memory.

FDTD scales poorly with domain size and wavelength ratio. FEM struggles with large, weakly-resonant structures and open boundaries. Both force compromises long before the design question is answered: reduced domains, symmetry assumptions, coarser meshes, fewer parameter sweeps.

The cost is not measured only in compute hours - it is measured in fabrication iterations that should not have been needed.

WaveSim Pro removes these bottlenecks

Simulate your full design, not a simplified version of it. Stop shrinking the simulation to fit the solver. WaveSimPro handles the structures your current tools cannot — so you work with the actual design, not an approximation of it.

Get results fast enough to guide decisions. Design exploration, parameter sweeps, and optimisation happen during the working day - not between working days. Faster simulation means more iterations, better designs, and shorter project timelines.

Reduce fabrication risk. Higher accuracy at full scale means fewer surprises when you go to manufacturing. Every fabrication cycle you eliminate saves weeks of schedule and significant cost.

Simulations that just work. Every simulation runs to completion. No failed runs, no troubleshooting, no time lost diagnosing solver issues.

MBS at its coarsest settings 7 seconds, 1.8% error

FDTD at its best tested settings 16 hours, 30% error

WAVESIM PRO

Photonic Simulation at Scale

WaveSimPro is a commercial photonic simulation platform built on the Modified Born Series (MBS), a frequency-domain method for solving Maxwell and Helmholtz equations.

The platform is available as a web-based application running on GPU-accelerated cloud infrastructure, or as an on-premises solution for organizations requiring local deployment, enhanced data control, or integration with internal HPC infrastructure.

Set up simulations interactively through the web interface in the cloud version, or the local GUI on-premise, or automate them via Python and MATLAB APIs.

WaveSimPro Cloud Python Starter Kit

Access WaveSim Pro Cloud from Python: set up your simulation locally in a script, run it on the cloud, and receive results as standard arrays. The Starter Kit on GitHub includes runnable Helmholtz and Maxwell examples and helper utilities.

Get Started

It maintains accuracy as designs grow in size and complexity

Runs every simulation to completion without convergence failures

Requires significantly less memory than conventional FDTD approaches for the same structure

High index contrast drives developed multiple scattering (cyan = slab faces)

APPLICATIONS

Built for the Problems Your Current Tools Can't Reach

WaveSimPro serves engineering teams and research groups working on photonic structures at wavelength scale, where domain size, index contrast, or accuracy requirements push FDTD and FEM past their practical limits.

Integrated Photonics

Waveguides, couplers, splitters, resonators, and photonic circuits at scales where grid-based solvers run out of memory.

Metamaterials & Metasurfaces

Metalenses, plasmonic structures, and sub-wavelength elements with full polarisation, no domain-size compromise.

Micro-Optics

Microlens arrays, beam shapers, and diffractive elements, simulated at full aperture in a single run, not broken into fragments.

Diffractive Optical Elements

Phase plates, holograms, and light-shaping optics with no accumulated dispersion error across the full domain.

Biomedical Imaging

Tissue scattering, OCT, and microscopy optics, accurate light propagation through complex, high-scattering media.

Nano-Optics & Sensors

Biosensors, near-field optics, and nanostructured devices where high index contrast defeats conventional methods.

WHY WAVESIM PRO

A complete simulation platform, not just a solver

Method advantages

Properties of the Modified Born Series that current solvers can't offer

No numerical dispersion

A frequency-domain method with no finite-difference approximation of derivatives - and therefore no accumulated discretisation error. Accuracy holds as designs grow larger and more complex.

Low Memory Footprint

Memory use is around 2% of an equivalent FDTD simulation. Wavelength-scale 3D problems that don't fit in the memory of conventional solvers run on a single GPU.

Fast Time-to-Result

Wavelength-scale 3D simulations typically complete in seconds to minutes. Parameter sweeps and design iterations that would otherwise take days run within a working session.

Guaranteed Convergence

The Modified Born Series is mathematically proven to converge for arbitrary dielectric structures, including high-index-contrast and strongly-scattering media. No preconditioner tuning, no stalled solves, no diverged runs - every simulation returns a result.

Workflow integration

Standard formats and interfaces, so WaveSimPro fits into existing design pipelines

Compatible with open-source WaveSim

Designs and Python scripts from the open-source reference transfer directly to WaveSimPro, via the same API on a C++/CUDA engine with production optimisations.

Python & MATLAB APIs

Automate simulations, run parameter sweeps, and integrate with existing design and optimisation pipelines.

GDS, STL, xPDK & voxel geometry import

Work with the standard formats photonic design teams already use.

Platform

Everything needed to run, inspect, and manage simulations

Flexible access

Choose between instant access through any modern browser or an on-premises deployment integrated with your local infrastructure.

Project versioning & sharing

Track simulation versions, share projects with collaborators, audit design history across a team.

On-demand GPU compute

Simulations run on Rayfos-managed cloud infrastructure. Access high-performance compute without maintaining local hardware.

Interactive 3D visualisation

Inspect geometry and field distributions in 3D, 2D slices, or quad-view directly in the browser. No external post-processing required to see results.

WAVESIM vs WAVESIM PRO

Same method. Engineered for production

How does WaveSimPro Cloud relate to WaveSim?

WaveSimPro Cloud shares its scientific foundation — the Modified Born Series (MBS) method — with the open-source WaveSim library, but is built on a separate, performance-optimised codebase that delivers the speed and memory efficiency needed for large-scale 3D problems.

You get the same underlying method, combined with managed cloud infrastructure, operational reliability, and commercial support.

What changes when you move from WaveSim to WaveSimPro Cloud.

Infrastructure

No software to install

Skip the local setup and infrastructure. Simulations run on Rayfos-managed cloud compute resources, enabling large-scale wave propagation problems to be solved accessible directly from the browser.

Scale

Beyond local hardware

Run on Rayfos's high-performance GPU and CPU cloud infrastructure, offering fast compute and high memory for large 3D problems.

Performance

Faster and more efficient

Executes MBS simulations considerably faster and with a smaller memory footprint, pushing domain sizes even further.

Visualisation

Built-in 2D and 3D inspection

Interactive 3D views, 2D slices, and quad-view comparison of field distributions — all directly in the browser, with no custom plotting code required.

End-to-end

A complete loop in one interface

Model setup, simulation run, and field inspection happen in the same browser session — no exporting between tools, no separate viewer, no post-processing script to write.

Team

Built for collaboration

Share projects with colleagues through the browser—without file transfers or version mismatches. Teams can review, update, and rerun simulations from anywhere, using the same project version every time.

Bring your own

Designs and results from your tools

Import complex designs from standard CAD, photonics, and scientific formats. Or open simulations you have already run with the Python or MATLAB APIs and visualise their results in the same web GUI.

Support

Commercial backing

Benefit from ongoing updates, technical support, and a continuously improving platform backed by Rayfos.
