When heat interferes: A data-driven workflow to analyze thermal crosstalk in PIC switch networks
Webinar
演讲嘉宾
To meet the escalating bandwidth requirements of AI clusters and data center interconnects, the industry is rapidly pivoting towards advanced optical communication solutions. By bringing the electro-optic interface closer to electronic chips that process the data, and enabling high-speed communication with a low cost per bit, PICs have become one of the key enablers of next-generation computing architectures.
At the heart of these systems are complex optical switching networks, which are used to redirect light signals from one destination to another. These networks often rely on active components, such as thermo-optic MZI switches, to steer light between outputs. While this approach offers flexibility and scalability, real-world implementations face a challenging tradeoff between limited chip area, accumulated optical losses, and crosstalk between the channels.

Although losses and crosstalk are often estimated using simple frequency-domain simulations, the impact of the spatial heat distribution is difficult to calculate. It can ultimately dictate key architectural and layout decisions and significantly impact device performance.
In this webinar, we’ll show you how you can estimate the impact of the parasitic thermal effect by using the Layout-Aware Variability Analysis in the Luceda Circuit Analyzer. You will learn how to:
- How to design and leverage parametric circuits in Luceda IPKISS
- Set up and run layout-aware variability analysis simulations
- Leverage Luceda’s data-driven workflows to efficiently perform such analyses
- Perform tradeoff analyses using Circuit Analyzer to guide robust design decisions
Join us to gain practical insights into thermal crosstalk analysis and learn how Luceda Photonics can help you design more scalable, reliable photonic switch networks before committing to fabrication.
