| heal.abstract | This paper presents a theory for the operation of thin-film thermo-optic bistable devices. Special attention is paid to free-standing films. After a review of nonlinear Fabry" Perot resonators and how they work we solve the heat equation in the thin film subject to a heating effect. Switching speed and optical power consumption are functions of the rate of change of temperature in the presence of a heat source. The interplay of heat loss from the surface of the film with heat diffusion within the film complicate the dynamics considerably. Quantitative results are derived for the dependence of speed and power on the dimensions of the active region of the optical element. It is found that diffusion transients can effect more rapid switching at the expense of power but only for infrequent operation. | en |
