A demonstration of a new scheme of optical bistability without involving light interference effects is presented. The nonlinear feedback involves the phenomenon of selective reflection in a film of a thermochromic liquid crystal, its temperature dependence and the sample heating by absorption of the transmitted light. It is shown that this scheme may be included into the family of systems exhibiting the so-called increasing absorption bistability. © 1991.
