Photon Design showcasing simulation tool innovations at Photonics West
In booth 3452 at SPIE Photonics West 2026 in San Francisco, CA, USA (20–22 January), photonic simulation CAD software developer Photon Design Ltd of Oxford, UK is highlighting its latest innovations, HAROLD (QD), MT-FIMMPROP and EPIPPROP. The firm’s simulation tools will also be featured in academic presentations and commercial demonstrations elsewhere at the show.
Photon Design’s EME simulators enable rapid, 3D simulations with minimal processing overheads. A standard laptop PC will take only minutes to process EME simulations where industry-standard, FDTD-based simulations would take many hours, often utilizing expensive cloud resources.
“The HAROLD (QD) simulator is used to design epitaxy structures in quantum dot lasers. QD lasers are essential to the development of next-generation data centers, AI and HPC applications, due to their high-temperature reliability, modulation, data transmission, heat reduction, and power efficiency benefits,” says CEO Dr Dominic Gallagher. “Next we have the new Multi-Topology (MT)-FIMMPROP simulator, which supports the native design of pioneering TFLN, Mach-Zehnder modulators, essential for high-data-rate photonics applications. Finally, the updated EPIPPROP simulator streamlines the design of arrayed waveguides (AWGs), with a slot waveguide option for polarization-sensitive applications coming soon,” he adds.
Photon Design’s FIMMPROP simulation tool will feature in Aalto University’s Dr Paul Verrinder’s presentation ‘Regrowth-free, monolithic integration platform on GaAs using vertical twin waveguides’, where it simulates a gallium arsenide, near-970nm, monolithic platform used for developing active-to-passive coupling tapers between vertically separated waveguides. (20 January at 5:20pm in Room 3022, Moscone West, Level 3).
FIMMWAVE has also been used by Dr Juniyali Nauriyal, CEO of Photonect (www.photonectcorp.com) for developing laser-assisted, fiber-to-chip optical interconnect technology, demonstrated at the Nextcorps LUMINATE, booth 258. By eliminating the need for epoxy, highly efficient coupling is achieved, with FIMMWAVE simulated losses below half a dB per facet, at 1310nm, when coupling to third-party, photonic devices.
