Reconfigurable integrated circuits draw the attention of the quantum optics community, because of their remarkable capability to set up different experiments on a single device. While universal reconfigurable integrated circuits are usually fabricated lithographically, this work demonstrates a less expensive, faster femtosecond-laser-writing technology for creating programmable photonic circuitry, thus opening up their usage to a wider audience.
