Reconfigurable Photonic Platforms: A Lithography‐Free and Field‐Programmable Photonic Metacanvas (Adv. Mater. 5/2018)

In article number 1703878, Jie Yao, Junqiao Wu, and co-workers demonstrate a lithography-free, rewritable metacanvas, on which nearly arbitrary metaphotonic devices can be rapidly and repeatedly written and erased. The writing is performed with a low-power laser. The metacanvas opens up possibilities where photonic elements can be field-programmed to deliver dynamic, complex, and system-level functionalities.
