Abstract
We determined switching times vs. excess power of a thermooptical bistable self-electro-optic effect device (SEED), operating as a logical AND gate. The transient behaviour is mainly determined by heat diffusion in the sample. Observed switching times are compared with a numerical solution of the heat diffusion equation. It is shown, that the frequently used relaxation-time-approximation, with its assumption of a constant relaxation time, is in good agreement with the experimental data only in the "ON-switching" mode of the SEED-element. For the "OFF-switching" of the device, the change of the shape of the transversal temperature profile has to be taken into account.
