From foundry PDK to
verified and manufacturable chip

PhotonForge is the complete platform for photonic integrated circuit design: schematic capture, layout, multi-physics + circuit simulation, inverse design, verification, and yield analysis, all in one place. Work from the GUI, from Python, or hand the whole loop to an AI agent.

01 · The toolbox

Everything You Need, from Idea to Tape-Out

and you do not even have to drive it yourself…

02 · The AI co-designer

Agentic Photonic Design

PhotonForge was built so humans and AI co-design chips end to end. Describe what you need in plain language and FlexAgent runs the same layout, simulation, and verification tools an engineer uses: it builds components, runs the physics, inspects the results, and iterates until your target is met.

03 · One source of truth

Traceable and Collaborative by Default

Whether you drive the tools or the agent does, every component, schematic, layout, and simulation result lands in one shared, version-controlled project. Changes are tracked, results stay traceable to the exact design that produced them, and your whole team works from the same source of truth.

Testimonials

Recommendations from our customers

"We believe that PhotonForge is the right approach to photonic circuit simulations. It allows us to accurately simulate components with the powerful Tidy3D engine and seamlessly integrate them into circuits and layout, using Python code or the GUI. [...] This opens up new options for our designs and also saves a lot of time. As a startup the credit system helps us not spending more than we need, and the support has been superb."

Miguel Carro Temboury
Senior Optical Design Engineer at Bifrost Communications

"With PhotonForge it's extremely simple to define the material stack of any integrated photonics technology, and validating the operation of photonic building blocks or whole circuits is a matter of a few lines of code. Similar to Tidy3D, the engineer's task is facilitated by top-notch documentation and examples, and by excellent customer support by the tool developers themselves."

Alberto Beccari
Head of Photonic Design at Luxtelligence

"PhotonForge provides us with intuitive integration to Tidy3D, easy scripting and 3D viewing of complex photonic circuits, in addition to robust automation features, such as automatic port detection based on path profiles and automated simulation boundary definitions. Combined with the extensive component library, the user-friendly GUI simplifies our design and debugging process, while also allowing us to leverage the FDTD performance offered by Tidy3D.”

Quick Start

PHOTONFORGE
FEATURES

PhotonForge provides a complete photonic design automation platform, combining layout generation, circuit simulation, and foundry PDK integration into a single system. The platform supports real-world photonic integrated circuits and prepares consistent, fabrication-ready designs across foundries and use cases, for both interactive design workflows and automated pipelines.

01

Foundry PDK Integration

Integrates directly with foundry process design kits, enabling designers to work within real fabrication constraints from the start. Technology definitions, layer mappings, and design rules are applied automatically, ensuring that layouts are fabrication-ready without manual checking.

Foundry PDK Integration
02

Hierarchical Component Design

Supports hierarchical design of photonic components, from individual waveguides and couplers to complex multi-level circuits. Components can be composed, parameterized, and reused across designs, enabling scalable photonic circuit architectures with consistent behavior and verified connectivity.

Hierarchical Component Design
03

Circuit simulations in both frequency and time-domain

PhotonForge computes photonic components using Tidy3D's GPU-native multiphysics solvers, captures coupling, scattering, and mode behavior with high fidelity, and provides reliable performance data for circuit-level analysis and design optimization in both frequency and time domains.

Circuit Simulation
04

Powerful GUI Interface: Photonic Canvas

Photonic Canvas, the intuitive GUI of PhotonForge, redefines the design experience by unifying the entire development cycle within a single, streamlined interface. Engineers can seamlessly transition from schematic-driven layouts to fabrication-ready GDS files while running high-performance simulations in real time.

Photonic Canvas GUI
05

Example Library & Reuse

Includes a growing library of pre-built photonic components, devices, and chip layouts, and enables teams to build custom component libraries with verified simulation models. Reusable components accelerate design cycles and ensure consistency across projects and team members.
