摘要：

This letter reports the operation of single- and multipoint active fiber sensors for both strain and temperature measurements. An active fiber source consists of a pair of wavelength-matched Bragg gratings formed in a rare earth doped fiber, and when optically pumped, lase in a narrow bandwidth around the Bragg wavelength. The primary advantage of an active sensor over a passive sensor is a significant increase in signal-to-noise ratio.
