Abstract :
We show that a semiconductor optical amplifier based nonlinear loop mirror with optical feedback can have two stable modes of operation at 10 GHz and 20 GHz. It can act either as an all-optical circulating shift register with inversion or as an all-optical clock divider, depending on the relative timing of the switching pulses
