Optical switching via waveguided gold nanowires is achieved. This is possible due to the transient red‐shift of the plasmon resonance of the gold nanowires under strong optical excitation and its coupling with the waveguide resonance mode. The effect can be tuned over a broad range in the visible region by changing the angle of incidence.
