Phys. Rev. Lett. 83, 2328–2331 (1999)Convection versus Dispersion in Optical BistabilityReceived 24 March 1999; published in the issue dated 20 September 1999 We analyze experimentally the combined action of convection and a diffusionlike process in a bistable nonlinear optical resonator. We show that the very existence of bistability in this device strongly depends on a competition mechanism between these two processes. This mechanism is described analytically in terms of the switching wave dynamics of a Fisher-Kolmogorov equation. © 1999 The American Physical Society URL:
