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.

光子集成电路：通过响应性聚电解质多层覆层可逆编程的光子（高级光学材料16/2020）

Ilja K. Voets，Oded Raz和同事在文章编号2000325中，探索了一种使用响应式聚电解质多层（PEM）包层的可编程光子学方法。通过连续暴露于酸性和中性pH溶液，PEM可逆溶胀，可以控制薄膜的孔隙率。所产生的折射率变化被用于对光子器件进行编程，该光子器件在两种不同的状态之间运行，这些状态实际上是无损且非易失的。这些结果是迈向PEM辅助的可逆可编程多用途光子集成电路的第一步，以实现低成本大规模制造。
