Optical Bistability in Four-Level Nonradiative Dyes

Zhen Fu Zhu, E. Garmire

Most saturably absorbing dyes show a large unstaturable loss which removes the possibility of purely absorptive bistability. However, nonradiative dyes such as those used for Q-switching have an intensity-dependent phase shift which may allow bistability. We will show that this nonlinear refractive index comes from the population redistribution during saturable absorption.

Optical Bistability in a Nonlinear Resonator with Saturable Losses and Intensity-Dependent Refractive Index

S Bhargava, Claudio Porzi, Prasanta Kumar Datta +3 more

We present numerical results relative to a bistable optical device comprised of an asymmetric Fabry-Perot cavity embedding a nonlinear optical medium. Both the real and imaginary part of the third order nonlinear susceptibility are considered in our calculations. Optimized device operation, expressed in terms of the contrast ratio between the two stable states, is then discussed as a function of the different cavity parameters. The presented method can be a useful tool for designing practical devices with application in the field of all-optical switching, optical regeneration and optical signal processing.
