Photon Design showcasing laser simulation tool developments at Optica Laser Congress
On stand 142 at the 2025 Optica Laser Congress and Exhibition in Prague Congress Centre, Czech Republic (19–23 October), photonic simulation CAD software developer Photon Design Ltd of Oxford, UK is presenting updates to three of its laser simulation tools: a quantum dot (QD) module for HAROLD; a PCSEL (photonic crystal surface-emitting laser) solution using HAROLD and OmniSim; and the PICWave photonic integrated circuit (PIC) design tool.
“Quantum dot lasers are at the forefront of next-generation LiDAR, datacoms, AI and HPC, due to the size, heat and power savings they offer in high-power laser applications,” notes CEO Dr Dominic Gallagher. “Our HAROLD simulation tool now includes a quantum dot module, enabling engineers to model epitaxy structures, dot size, and istribution, with gain and absorption spectra results reliably matching real-world lasers,” he adds.
“Our PCSEL solution integrates HAROLD and OmniSim to deliver high-power, coherent laser sources. HAROLD simulates a range of epitaxy structures, while OmniSim uses FDTD modelling to simulate light propagation and gain. Lastly PICWave, which is a photonic integrated circuit (PIC) design and simulation tool, integrates laser diode and SOA [semiconductor optical amplifier] modelling within a flexible, design flow environment,” Gallagher continues.
“Enhancements to our PICWave and HAROLD laser simulation tools have been partly enabled by the addition of an application engineering function to our development team. This strategic change has enabled us to accelerate the launch of new features and improve the performance and productivity of our simulations, further strengthening Photon Design’s position as a leader in laser design.”
