Periodic nanostructuring can enhance the optical nonlinearity of plasmonic metals by several orders of magnitude. By patterning a gold film, the largest sub‐100 femtosecond nonlinearity is achieved, which is suitable for terahertz rate all‐optical data processing as well as ultrafast optical limiters and saturable absorbers.
