Abstract: PURPOSE: A temperature sensor using an MMF interferometer and a method of measuring the temperature of the sensor are provided to lower the manufacturing cost of a temperature sensor and enable accurate measuring of temperature since a temperature sensor with the same function can be manufactured using the MMF interferometer of TMF without FBG. CONSTITUTION: A temperature sensor using an MMF interferometer comprises a light source, a first MMF interferometer(150-1), a second MMF interferometer(150-2), a photo coupler(140) and an operation unit(180). The first interferometer is located on a target. The second interferometer is located on other places than the target. The photo coupler distributes light from the light source and transfers it to the first and second interferometers. The photo coupler couples lights reflected from the first and second interferometers. The operation unit calculates the temperature of the target based on the light output from the photo coupler.

Abstract: PURPOSE: A solar lighting optical fiber module using a large core optical fiber is provided to secure high durability against high temperature while preventing environmental pollution since there is no epoxy. CONSTITUTION: A large core optical fiber and a connector for an SMA fix an optical fiber without epoxy. The connector for SMA is comprised of an SUS ferrule and a fitting and has high durability against high temperature and energy. The fitting fixes the optical fiber in the SUS ferrule by forming the hole for locking a screw to be narrower.

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.
