摘要： A multi-cladding optical fiber, a long-period optical fiber grating written in the optical fiber, and a writing method thereof are provided. The multi-cladding optical fiber includes a core made of germanium-doped silica (GeO2—SiO2), for guiding light, an inner cladding made of fluorine-doped silica (F—SiO2), the inner cladding having a refractive index smaller than that of the core and surrounding the core, and an outer cladding made of silica, the outer cladding having a refractive index smaller than that of the core and larger than that of the inner cladding and surrounding the inner cladding. Therefore, an optimized optical fiber can be designed. That is to say, an optical fiber having desired characteristics can be fabricated by adjusting at least one of the parameters including the amount of F doped into the inner cladding, the thickness of the inner cladding, the amount of GeO2 doped into the core, the composition of SiO2 in the outer cladding and the drawing tension of the optical fiber. Also, the refractive index of the core is periodically changed by periodically annealing the multi-cladding optical fiber, so that a stress-released long-period optical fiber grating can be obtained.

摘要： An erbium-doped optical fiber (EDF) and a fabricating method thereof The erbium-doped optical fiber has a core formed by substantially doping silica with erbium and having gratings formed therein at a predetermined period, for propagating light therethrough, and a cladding surrounding the core and having a lower refractive index than the core. Since the erbium-doped optical fiber acts as a gain flattening filter, an erbium-doped fiber amplifier formed out of the erbium-doped optical fiber obviates the need of splicing an erbium-doped optical fiber with a gain flattening filter.

摘要： Disclosed are a Raman or erbium-doped fiber laser using a few-mode fiber grating, and a long-distance remote sensor using the same that can simultaneously measure temperature and strain by separating temperature and strain components using Raman amplification or erbium amplification. When a multi-wavelength Raman or erbium-doped laser is configured by means of a short-period fiber grating serving as a few-mode fiber grating at one side of a resonator and a chirped fiber Bragg grating or tunable chirped fiber Bragg grating at the other side of the resonator, multi-wavelength laser signals are generated in different modes. Because wavelength shift and reflectivity vary with a change in temperature and strain, temperature and strain components can be simultaneously measured. Because an optical fiber of several tens of kilometers is used, it can be utilized as a sensing probe of the long-distance remote sensor.
