A signal-regenerating optical-fiber loop memory with a side-injection-light-controlled bistable laser diode exhibiting thresholding gain characteristics is demonstrated. This system digitally regenerates memorized signals bit by bit. Output signals with a high on/off ratio of around 20 dB and stable intensity levels with less than 7% fluctuation are obtained even after 100 circulations.
