Observation of Optical Bistability Hysteresis Loop with Surface Waves in Doped Polymer Film

Abstract

Optical bistability hysteresis loop has been observed experimentally with a setup using prism excitation of surface wave in a doped polymer thin film. A simple model has been developed to analyze its operation. The observed bistability hysteresis loop can be explained in terms of surface plasmon excitation and laser induced refractive index variations.

Optical bistability has been observed with nonlinear long-range surface plasmons excitation using prism-index matching liquidsilver film-semioonduotor-doped glasses configuration by ATE. A typical hysteresis loop has been recorded for the relation between reflectance and incident beam power.

Observation of Optical Bistabilities in a Doped Polymer Thin Film Quasi-waveguide

Wang Huitian, 董凤忠 Dong Fengzhong, Zhanxiang Zhang +5 more

Optical bistability was observed and studied in the output of reflected beam as well as in that of m -lines in a doped polymer thin film quasi-waveguide. The physical origin was demonstrated to be the existence of a mode spectrum and the high third-order nonlinearity of the polymer film. It was also observed for the first time that the intensity variation of the reflected beam and the m -line in the hysteresis loops are complementary to each other.

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

Zhanxiang Zhang, Hui‐Tian Wang, Peixian Ye +2 more

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.

All-optical bistability in doped-polymer film waveguides

Hui‐Tian Wang, Peixian Ye, Ling Qiu +2 more

All-optical bistability was observed in thin-film waveguides made with acceptor-donor substituted azobenzene-doped poly(methyl methacrylate) polymer. Input-output curves with hysteresis characteristics were measured. The origin of the bistability was attributed to nonlinear coupling between a prism and a doped-polymer waveguide. An approximately theoretical analysis was introduced. Theoretical predictions were qualitatively consistent with experimental results.
