[Boston, Sep 12, 2025] – Flexcompute today announced the release of its RF solver on the Python client, a significant step in bridging radio-frequency (RF) and photonic simulations for integrated chip design. This powerful addition to the Flexcompute platform allows researchers and engineers to seamlessly combine electromagnetic and circuit-level modeling, streamlining the design of next-generation photonic integrated circuits (PICs).

Flexcompute RF provides a unified environment where users can:

• Simulate high-speed modulators and impedance-matched interconnects with accuracy and efficiency.

• Analyze coplanar waveguide property in an integrated circuit or individual device.

• Analyze electro-optic interactions, such as modulation efficiency, to optimize device performance.

• Perform signal integrity studies, identifying and resolving transmission bottlenecks.

With direct integration into Tidy3D’s multiphysics solvers, RF enables end-to-end photonic design automation—from device-level physics to system-level performance. It also supports inverse design workflows, allowing users to optimize layouts and achieve fabrication-aware designs with unprecedented ease.

“Photonic integration demands tight coupling between optical and RF domains,” said Dr. Prashanta Kharel, the Technology Strategist at Flexcompute. “By bringing RF simulation to the Python client, we’re empowering researchers and engineers to accelerate design cycles, reduce risks, and innovate faster in photonic integrated circuits.”

The new RF solver is now available through Flexcompute's Python client on the Electromagnetic platform, providing both accessibility and scalability for users working in cloud and on-premise environments.
