A Thermally-Tuned PIC with External Light Coupling: Design and Layout

Photonic Integrated Circuits (PICs) are becoming increasingly important in many areas including communications, remote sensing and medical applications.

Designers active in this field rely on simulation to study and optimize a circuit, even before the prototype stage. Simulating such circuits can be challenging due to their large size in relation to the wavelength of interest and need for multiphysics simulation. Another important challenge in all PICs is efficiently coupling the external light into the chip. The two major methods are surface coupling and edge coupling.

In this eSeminar, Dr. Kabiri from 4Catalyzer will present how a diffraction grating coupler for surface coupling can be designed and optimized using a combination of Luceda Photonics IPKISS and CST Studio Suite®. High Performance Computation (HPC) is used to speed up simulation of the ultra-large simulation domain and find the optimum performance. ...

This eSeminar will also show how parameters characterizing active devices, such as a thermally-tuned ring resonator, can be automatically extracted from simulation using a similar workflow.
