In order to study the influence of temperature on the depolarization performance of optical fiber Lyot depolarizers accurately, based on the structural parameters of fiber depolarizers provided in previous references, an optical fiber Lyot depolarizer was made with a polarization maintaining fiber welding machine and its degree of polarization (DOP)P≤0.5% under the total temperature conditions(-40℃~80℃). The test system of the output DOP of the depolarizer under constant and variable temperature conditions was built. The causes of the change of DOP were analyzed. The measurement results show that the output DOP of the depolarizer remains unchanged basically when the temperature is constant at -40℃ and 80℃.The output DOP will change when the temperature changes at a certain gradient. The study has a certain reference value for the research in optical fiber sensing application.
