Low-power and broadband optical bistability by excitation of surface plasmons in doped polymer film

Abstract

The low-power and broadband optical bistability in an acceptor–donor-substituted azobenzene-doped polymethyl methacrylate thin film, which relies on the excitation of surface plasmons with a cw laser of several tens of milliwatt power, is studied experimentally and theoretically. The observations on the characteristics of the bistability are essentially consistent with the theoretical predictions.
