We report the first all-optical power limiter based on cascaded InSb étalons. The power limiting effect is due to a dispersive nonlinearity in InSb at room temperature as a result of generation of free carriers through two-photon absorption of 10 µm radiation. The efficiency and dynamic range of this all-optical circuit are discussed.
