Silicon carbide (SiC) is a promising material platform for photonic integrated circuits (PICs) and miniaturized solid-state quantum systems. In the ALP-4-SiC project – Atomic Layer Processing for SiC for Applications in Photonics and Quantum Communication – researchers from the Max Planck Institute for the Science of Light (MPL) and the Fraunhofer Institute for Integrated Systems and Device Technology IISB are jointly developing basic technologies for the production of highly efficient photonic circuits. Using optical waveguides and ring resonators as examples, they are demonstrating how atomic layer processing (ALP) can be used to significantly improve the optical properties of photonic devices made of SiC. ALP-4-SiC is 100% funded by the German Federal Ministry of Research, Technology, and Space (BMFTR) as part of the “Scientific Preliminary Projects” (WiVoPro) initiative.
