A fast and low‐power all‐optical tunable Fano resonance in a plasmonic microstructure made of gold and polycrystalline LiNbO 3 is realized by combining strong quantum confinement enhancing nonlinearity and near‐resonant excitation enhancing nonlinearity. The operating pump intensity is reduced by four orders of magnitude, while a fast response time on the order of a hundred picoseconds and a large tunability are maintained.
