Phase‐change materials are an established material for data storage applications and promising for active photonics. However, the common laser‐induced switching between the different structural states of the material is restricted due to the diffraction limit. In article number 2001243, Ann‐Katrin Michel, Dmitry Chigrin and co‐workers propose local switching by a heated scanning tip. Thereby, a highly‐resolved tunable metasurface with perfect absorption in the telecommunication range can be created. The authors further investigate the time‐resolved switching conditions by using multiphysics simulations.
