Photonic integrated circuits (PICs) can be realized on many different technology platforms and used for numerous different applications. This course focuses on the so-called Thick-SOI platform and its use for sensing and imaging applications in the near and mid-infrared region. Primary focus is on 3 µm thick silicon-on-insulator (SOI) waveguide technology, which is the most mature PIC technology platform at VTT. This platform is also available for small-to-medium volume contract manufacturing via VTT and there is a path to large-volume manufacturing via Rockley Photonics. Process design kits are available in multiple PIC design software platforms.

This one-day hands-on training course provides industry an overview of the Thick-SOI PIC platform and its feasibility in sensing and imaging applications. A clean room tour in Micronova offers an overview of the used fabrication methods and facilities. Hands-on training includes 1) the design of 3 µm SOI PICs using PIC design software, 2) wafer-level testing (WLT) in the clean room and 3) PIC testing in the photonics measurement lab. The last part includes semi-automated fiber-to-waveguide alignment, optical beam steering with an optical phased array (OPA) and one sensing demonstration that varies from training to training and may include e.g. Faraday rotation in SOI waveguides or gas sensing with a tunable light source.

It is desirable but not essential that course attendees have a basic understanding of photonics. The course is ideally suited to those planning to develop new photonic products based on low-loss photonic integrated circuits (PICs) operating within the 1.2-6 µm wavelength range where the thick (µm-scale) silicon-on-insulator (SOI) waveguides can operate.
