Optical bistability of partial reflection-coated thin film of oil red O.

In this paper, a thin film of oil red O coated by partial dielectric mirrors (PRFORO) operating as an optical bistable device is proposed. The equation of the output-input intensity relation considering nonlinear absorption inside PRFORO is derived and the optical bistability (OB) of PRFORO is shown. Additionally, the influence of the nonlinear refractive, absorptive coefficients of oil red O (ORO), reflective coefficient of mirrors, and the thickness of thin film on the OB is numerically investigated and discussed.
