Abstract
We developed and demonstrated a highly sensitive fiber Bragg grating (FBG)
temperature sensor by using the PbO-GeO$_{2}$-SiO$_{2}$ glass optical fiber. Temperature sensitivity of the FBG sensor
based on the PbO-GeO$_{2}$-SiO$_{2}$ glass optical fiber was about 40% improved to the 0.0173 nm/$^{\circ}$C by the thermal expansion increase of the fiber.
