We present some numerical calculations on the effect of diffusion and diffraction on the switching characteristics of bistable optical 6talons, together with an approximate analytic model demonstrating the major features and a discussion of switching waves in such systems. A diffusion length of one third of the input-beam spot size gives large hysteresis, whereas diffraction alone gives no hysteresis in first order.
