Research output: Contribution to journalConference articlepeer-review


A novel time-division-multiplexed Bragg grating interrogation system is presented, utilising a semiconductor optical amplifier within a resonating cavity. Without fast electronics, closely spaced low reflectivity gratings are interrogated with high signal power and low noise.
