The first online workshop on OPOSSUM – the Open Source Optics Simulation System and Unified Modeler – will take place on Wednesday, 4 June 2025, from 2-4 pm CEST via Zoom. The event will provide a first look at OPOSSUM, developed within the European THRILL project.

While OPOSSUM is still in its early development and design phase, this online workshop will provide an introduction to its core concept, a demonstration of initial capabilities, and a discussion of potential features. More importantly, we want to hear from you-our future users. Your insights and needs will directly shape OPOSSUM’s roadmap by guiding feature prioritization and development.

The following topics will be covered:

• Introduction to OPOSSUM and its vision
• Demonstration of current capabilities
• Discussion on feature development and roadmap
• Community-driven contributions and plugin system concepts

Whether you are a researcher, engineer, or developer in optics and photonics, your input will be invaluable in shaping the future of open-source optical simulation. We envision a collaborative ecosystem where community contributions integrate seamlessly into OPOSSUM’s framework.
