We study the multi-longitudinal mode instability in purely absorptive optical bistability in the limit of nonlinear absorber much thinner than one wavelength. Under that assumption the dynamical equations are space-independent difference-differential equations which allow for an analysis as simple as for the ring cavity, with two additional parameters related to the position of the absorber in the cavity. Different instability scenarios are found as the relative position varies.

Abstract
We study the multi-longitudinal mode instability in purely absorptive optical bistability in the limit of nonlinear absorber much thinner than one wavelength. Under that assumption the dynamical equations are space-independent difference-differential equations which allow for an analysis as simple as for the ring cavity, with two additional parameters related to the position of the absorber in the cavity. Different instability scenarios are found as the relative position varies.
