We present and analyse a new method for achieving all-optical bistability, in metal mirrored Fabry-Perot cavities containing thermo-optic material. It is shown how "butterfly" bistability is achieved in metal/metal mirrored cavities. Optimisation for low switching powers is considered for a dielectric/metal mirrored cavity. The use of nematic liquid crystals with such a system makes submilliwatt switching powers easily achievable.
