Photon Design, a global leader in photonic simulation CAD software, has announced that its quantum dot module for its HAROLD laser simulation tool, is now available as a release candidate for customer evaluation. The HAROLD module enables engineers to model a quantum dot (QD) laser's epitaxy structure, including dot size and distribution. Its eight-band K.P-based modeller predicts laser gain and absorption spectra, reliably matching the results of beta sample, quantum dot lasers in recent field tests.
Dr. Dominic Gallagher, CEO of Photon Design, said, “The HAROLD quantum dot simulator is at the forefront of quantum dot laser design. QD lasers operate reliably at higher temperatures than existing lasers, with superior modulation and data transmission performance, and heat and power savings. They also bring practical, silicon-based manufacturing benefits. Quantum dot lasers are expected to play a critical role in many, next-generation, laser applications, including supporting the move to optical architectures within data centres, AI, and HPC.
“The HAROLD quantum dot laser simulator is a release candidate which we are inviting customers to test and evaluate. It is a development of Photon Design’s long-established and well-respected, HAROLD, a mature simulation platform with an established library of material systems available to designers. When released, the HAROLD quantum dot module will have seamless integration into Photon Design’s PICWAVE simulator, giving engineers a full, three-dimensional, time evolving, quantum dot laser model.”
