Paper Abstract

Saturating absorption and optical bistability (OB) with ns switching time in Langmuir-Blodgett (LB) films of phthalocyanines derivatives on reflection have been studied at room temperature (RT) in the near ultraviolet region for the first time. The saturating intensity (Is) and switching intensity for the OB at 337.1 nm are about 1 MW/cm2 and 5 MW/cm2, respectively. The experimental results show that the major nonlinear and positive feedback mechanisms for the OB are the change of refractive index caused by the saturating absorption and the simple F-P cavity due to the natural faces of the sample, respectively.
