Time-division-multiplexing of fibre Bragg gratings using a novel resonant cavity architecture is described. Independent extraction of amplified optical signals from individual sensors is demonstrated, making it possible to use a low-cost, passive wav

The first resonant-cavity time-division-multiplexed (TDM) fiber Bragg grating sensor interrogation system is reported. This novel design uses a pulsed semiconductor optical amplifier in a cyclic manner to function as the optical source, amplifier, an

We report on the fabrication of in-fiber moire filters by dual exposure of a nondedicated chirped phase mask. This simple technique produces broadband filters whose structure depends only on an intermediate stretch between two identical UV exposures.
