Corrigendum to "femtosecond plasmon interferometer" [Opt. Commun. (2017) 382 509–513]
We haverealized a plasmonic interferometer formed by a nanoslit and a nanogroove in a single-crystal gold film. The possibility of measuring laser pulses of ultimately short durations, corresponding to two periods of a light wave (6fs pulse duration), has been demonstrated using this interferometer.
