Abstract: The effects of nonlinear absorption in optical bistability as observed at room temperature in Hg0.815Cd0.185 Te samples are investigated. As intensity is increased, a new feature for HgCdTe is observed, namely the transition in transmission from anti-clockwise hysteresis loops. This transition is not present in reflection. Our observations are consistent with the assumption of thermally induced changes in the nonlinear optical properties of the semiconductor.
