Abstract

Summary form only given. Discrimination of strain and temperature effects in fiber grating Bragg wavelength shift is a significant topic of recent research on fiber Bragg grating (FBG) sensors. In this paper, we present a simple sensor capable of simultaneous measurement of both strain and temperature using a single FBG written in Er/sup 3+/:Yb/sup 3+/ doped fiber (EYDF). We observed that the amplified spontaneous emission (ASE) power of the EYDF amplifier (EYDFA) has monotonically decreasing dependency on temperature in our range of measurement.
