Innovative new fabrication approach for reprogrammable photonic circuits

Modern society relies on technologies with electronic integrated circuits (IC) at their heart, but these may prove to be less suitable in future applications such as quantum computing and environmental sensing. Photonic integrated circuits (PICs), the light-based equivalent of electronic ICs, are an emerging technology field that can offer lower energy consumption, faster operation, and enhanced performance. However, current PIC fabrication methods lead to large variability between fabricated devices, resulting in limited yield, long delays between the conceptual idea and the working device, and lack of configurability. Researchers at Eindhoven University of Technology have devised a new process for the fabrication of PICs that addresses these critical issues, by creating novel reconfigurable PICs in the same way that the emergence of programmable logic devices transformed IC production in the 1980s.
