    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.

    摘要： A parallel optical fiber amplifier having a configuration in which a C-band silica-based erbium-doped fiber amplifier (EDFA) stage and an L-band EDFA stage are coupled together in parallel in such a fashion that a reverse amplified spontaneous emission (ASE) light emitted from the C-band and/or L-band EDFA stage is reused as a secondary pumping source for an amplification in the L-band EDFA stage. In the optical fiber amplifier of the present invention, the reverse ASE light emitted from the C-band EDFA stage and the reverse ASE light emitted from the L-band EDFA stages supplied to the L-band EDFA stage so that they can be reused for improving the power conversion efficiency of the entire system and for reducing the noise factor thereof.
