Abstract
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 mea sured. The origin of the bistability was attributed to nonlinear coupl ing between a prism and a doped-polymer waveguide. An approximately th eoretical analysis was introduced. Theoretical predictions were qualit atively consistent with experimental results.
