We investigate the spatial behavior of the electric field for optical
bistability in the good cavity limit. We show that stable spatially lo
calized solutions exist in one and two dimensions. In addition we find
that stable one-dimensional hole solutions also arise in this driven
non-eqilibrium system with dissipation and dispersion thus demonstrati
ng that stable holes are not restricted to dispersive systems, but can
emerge in strongly dissipative systems as well. A critical comparison
with the properties of stable localized solutions in other driven dis
sipative systems is also included.
