Collaboration on reprogrammable photonic chips using a polymer coating

Photonic integrated circuits promise high data transfer rates and offer possibilities in computing and sensing. A major bottleneck for their widespread implication has so far been a lack of simple and reversible programmability. A collaboration between the departments of Electrical Engineering and Chemical Egineering and Chemistry, led by Oded Raz and Ilja Voets, shows what is possible by coating photonic devices with a reversibly swellable polymer film. Recently promoted dr. Mahir Mohammed and PhD candidate Christian Sproncken combined their experiences in photonics and polymers, respectively, to fine-tune their new approach. The procedure is quick, straightforward and requires no continuous energy input, as is unfortunately the case for many other approaches.
