Abstract

It is known that the photoluminescence (PL) spectrum of the optical fiber temperature sensor, which uses the GaAs / GaAlAs double-heterostructure semiconductor as a transducer, is determined uniquely by the temperature of the transducer, and the changed range of the PL peak wavelengths is approximately from 0. 860 14 m to 0. 910 /2, m for the temperature range of 0-150 C, and the output signals of the sensor are nonlinear[ 1] .
