Abstract A spray deposited thin (6 μm) CdS film laser induced optical device (LIOD) was studied experimentally and theoretically. The all optical bistable (all-OB) and the hybrid bistable (HB) features at 210 K were investigated. It is shown for the first time that the observation of equal contrasted all-OB and HB loops is possible in thin CdS films. The slope of the all-OB loops were calculated with a new theoretical model which is established on the thermal enhanced shift of the absorption edge and the transmitted light equilibrium condition. A good agreement with the experiments is found. Furthermore, it is pointed out that the electron life time determines the fashion and the contrast of the HB loops. In this context the proof is furnished that the maximal possible HB loops is observed. Finally, the influence of Joule's heat on OB and HB is demonstrated.
