We describe the operating conditions under which a semiconductor optical amplifier based nonlinear loop mirror with optical feedback can have two stable modes of operation at switching rates faster than the gain recovery rate of the semiconductor optical amplifier. It can act either as an all-optical circulating shift register with inverter or as an all-optical clock divider, depending on the relative timing of the switching pulses.
