Photon Design previewing quantum dot simulation results at Photonics West
The company says its new tool allows simulation of gain and absorption spectra from epitaxy structures with multiple quantum dot layers
Photon Design, a developer of photonic simulation CAD software, is previewing results from its upcoming quantum dot module being added to their established laser simulator HAROLD at SPIE Photonics West. According to the company, the expansion to HAROLD 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, UK.
“HAROLD is a design tool for modelling the epitaxy layer composition of Fabry-Perot and VCSEL quantum well lasers,” said Dominic Gallagher, CEO and founder of Photon Design. “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. Photon Design provides consistent, technical support for tools like the HAROLD, including involvement with the developers themselves.”
HAROLD and the quantum dot module sit within Photon Design’s comprehensive CAD environment, a library of simulation tools for designing passive components (such as ring resonators, surface grating couplers and AWGs) up to entire active PICs, the company adds.
