Abstract
Optical bistability was observed and studied in the output of reflecte d beam as well as in that of m-lines in a doped polymer thin film quas i-waveguide. The physical origin was demonstrated to be the existence of a mode spectrum and the high third-order nonlinearity of the polyme r film. It was also observed for the first time that the intensity var iation of the reflected beam and the m-line in the hysteresis loops ar e complementary to each other.
