Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. A photonic integrated circuit (PIC) or integrated optical circuit is a device that integrates multiple (at least two) photonic functions and as such is similar to an electronic integrated circuit.
The major difference between the two is that a photonic integrated
circuit provides functions for information signals imposed on optical wavelengths typically in the visible spectrum or near infrared 850 nm-1650 nm. One possible technology platform for photonic integrated circuits is silicon, which, as the name implies, would use silicon as optical medium.
The main advantage is, that the Silicon photonic devices could be made using existing semiconductor fabrication techniques. Since silicon is already used as the substrate for most integrated circuits, it is possible to create hybrid devices in which the optical and electronic components are integrated onto a single microchip.
However, different fabs provides PDK for Silicon photonics. To create the layout for the Photonic components, we use IPKISS Luceda to facilitate the generation of such components. This components can be later imported and simulated in CST. The results can be read by IPKISS for further circuit simulations. Luceda verifies the analytical model (based on curve fitting to the full wavesimulations). Therefore, such one-time 3D full-wave simulations enable the photonic designer to obtain a valid analytical model, which accelerates further designing.
In this video, you will see the different solver choices offered by CST and a spectial attention is paid to material and port setup, which is critical in optical simulations. In addition, the Link between CST and IPKISS is explained and overall efficiency can be seen.
