Photon Design has enhanced its HAROLD QD simulation tool, more than halving computation times on standard workstations and laptops without requiring cloud processing.
The software is designed for three-dimensional simulation of quantum-dot lasers, enabling engineers to model quantum-dot structures, gain and absorption spectra, stress and strain, thermal rollover, carrier diffusion, current spreading and hole burning.
The faster simulations are intended to allow more design iterations while maintaining accuracy against field-tested quantum-dot lasers.
HAROLD QD also integrates with Photon Design’s PICWave platform, enabling dynamic 3D circuit simulation of laser architectures incorporating components such as DFB gratings, ring resonators, bends, tapers and directional couplers.
According to Photon Design CEO Dr Dominic Gallagher, quantum-dot lasers are gaining importance in applications including AI, HPC and optical data-centre architectures, where they can offer low power consumption, high-temperature operation and improved data transmission performance.
The company says HAROLD can also be used to simulate multiple-quantum-well structures and silicon modulators, forming part of its broader photonic design suite.
