Abstract: A temperature sensitive and photosensitive fiber, a temperature-insensitive and photosensitive fiber and an optical fiber sensor using the same are provided to reduce a manufacturing cost by not using a hydrogen loading method. A photosensitive fiber is composed of a core region and a cladding region. The core region is doped with the photosensitive dopant and the temperature sensitive dopant. The photosensitive dopant changes a refractive index of the core region by the UV laser irradiation. The temperature sensitive dopant increases the coefficient of thermal expansion of the core region.
