We have fabricated all-semiconductor-optical-amplifier loop devices and characterized their operation with cw signals. Gain saturation in the multi-mode interference (MMI) coupler led to nonlinear coupling and hence the power-dependent switching of the devices. The active loop is important to provide gain and to redistribute the field.
