In article number 2000325, Ilja K. Voets, Oded Raz and co‐workers explore a method for programmable photonics using a responsive polyelectrolyte multilayer (PEM) cladding. Reversible swelling of the PEM by consecutive exposure to acidic and neutral pH solutions yields control over the porosity of the film. The resulting refractive index changes are utilized to program photonic devices, which operate between two distinct states that are virtually lossless and non‐volatile. These results are the first step towards PEM‐assisted reversibly programmable multipurpose photonic integrated circuits for low‐cost mass‐manufacturing.
