Contact UsAnsys OPTI 301: Co-Packaged Lumerical & Zemax
Course Overview:
This course provides a practical, end-to-end introduction to designing and optimizing co-packaged optical systems using Ansys Lumerical and Ansys Zemax OpticStudio. Through hands-on examples, participants will learn how to simulate waveguide and fiber modes, model slab waveguide structures, and perform near-field data extraction, and leverage simulation results across both tools to optimize overall system performance.
Who should take this course:
This course is designed for engineers involved in the design, simulation, and optimization of co-packaged optical systems, including optical, photonics, and silicon photonics engineers who want to develop integrated workflows using Ansys Lumerical and Ansys Zemax OpticStudio. Students should already have a basic understanding of the software.
Core proficiencies:
By the end of this course, participants will be able to:
- Simulate slab waveguide structures and analyze TE/TM mode profiles and effective indices using Lumerical MODE.
- Extract and export near-field (zbf) data from Lumerical FDTD for downstream use in Zemax OpticStudio.
- Model optical propagation and fiber coupling in Ansys Zemax OpticStudio.
- Analyze single-mode and multimode fiber coupling performance.
- Evaluate the effects of beam characteristics and system tolerances on coupling efficiency.
- Transfer simulation data between Ansys Lumerical and Ansys Zemax OpticStudio.
- Optimize end-to-end co-packaged optical system performance using an integrated simulation workflow.
