Cavity optimisation in thermal optical bistability is analysed by considering bistable etalons with the absorption localized in one of the reflective coatings. The alternatives of front and back mirror absorption are theoretically compared and experimentally demonstrated with different organic liquids used as thermally-sensitive optical spacer. Steady-state bistable loops with submilliwatt powers are reported. © 1987.
