We theoretically and experimentally investigated the photoisomerization of azo chromophores and the resulting nonlinear optical response of transmission and four wave mixing through the two-energy-level model. The rising time constant of the transmission obtained by the model gave good agreement with that of the wave-mixing signal. In addition, we tried to improve the time response by using photoactive polymers ionic-bonded with azo chromophores.
