Photon Design to exhibit QD simulation tool
Photon Design, a UK developer of photonic simulation CAD tools, is showing the results from its upcoming quantum dot software module at SPIE Photonics West in San Fransisco (28th to 30th January 2025).
The module, which is being added to the company's HAROLD laser simulator, will allow simulation of gain and absorption spectra from epitaxy structures with multiple quantum dot layers using an eight band k.p model and a full 3D stress-strain model.
The module was developed and validated in collaboration with Cardiff University, one of the UK’s leaders in compound semiconductor photonics.
Dominic Gallagher, CEO and founder of Photon Design said: “HAROLD is a design tool for modelling the epitaxy layer composition of Fabry-Perot and VCSEL quantum well lasers. The new HAROLD quantum dot module enables rapid, virtual prototyping and performance verification of the absorption and gain spectra of the quantum dot layers, down to the sizes and distribution of the dots in the epitaxy. This will help inform and improve the supplier’s manufacturing process, linking real test results with the simulation model.”
HAROLD and the quantum dot module sit within Photon Design’s CAD environment; a library of simulation tools for designing passive components (such as ring resonators, surface grating vouplers and AWGs) up to entire active photonic integrated circuits.
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
