摘要： PROBLEM TO BE SOLVED: To provide a small collimator light source which emits polarized light having a small luminous flux diameter for a light sensor and has a simple structure for easy mounting.SOLUTION: A collimator light source has at least a refractive index distribution type fiber and a coreless fiber which are fusion-connected in a ferrule. Light is injected from a light source connected adjacent to the refractive index distribution type fiber through a lens and emitted from adjacent to the coreless fiber. The ferrule is provided with a slit above an inclined end of the coreless fiber in the ferrule, and an optical element is arranged on an end of the coreless fiber. The inclined end of the coreless fiber has an inclination angle such that the end is inclined to the vertical plane of the optical axis at Brewster's angle Θb1. The propagation light is reflected at the inclined end. The optical element is arranged on the inclined end, having an emission surface with an inclination angle α to the optical axis of the fiber. The reflected light from the inclined end of the coreless fiber is emitted approximately vertically to the optical axis of the fiber. The small collimator light source thus emits the emission light having a small luminous flux diameter and a high extinction ratio.

摘要： PROBLEM TO BE SOLVED: To provide an ASE light source of single peak spectrum of the wavelength band different from that in the related art, and also to provide the highly accurate single peak spectrum having wider half-value width. SOLUTION: The ASE light source comprises an excited light source and a rare-earth added fiber for generating the ASE light from the incident excited light. In this ASE light source, the rare-earth added fiber shifts the wavelength of generated ASE light by setting the length of the same fiber longer than that for generating the ASE light in the wavelength band of 1,565 to 1,605 nm. Moreover, light intensity for the wavelength in the long wavelength region of the shifted wavelength band is controlled to generate the ASE light of the single peak spectrum.

摘要： PROBLEM TO BE SOLVED: To solve the problems of a conventional contact type fiber sensor having a structure wherein an FBG is not completely stuck to a measuring part because the sensor does not have fundamentally a mechanism for pressing equally from above, wherein a distortion of the measuring part is not transferred to the FBG to thereby fail to function as the sensor in the case where the sensor is not stuck and fixed sufficiently and equally onto the measuring part, or a peak of a reflected waveform is distorted to thereby fail to measure a wavelength shift caused by the distortion when the FBG is unequally distorted in the length direction and fixed, or sometimes the sensor part easily peels off by fluctuation of the environment such as a temperature or a humidity because the sensor part is exposed to the external environment.
SOLUTION: A part having the fiber Bragg grating (FBG) of an optical fiber is fixed in a fixing layer, and both surfaces of the fixing layer are sandwiched by a sheet comprising an elastic material, to thereby form the FBG sensor part, and one surface of the FBG sensor part is stuck to the measuring part through a sticking layer, and a pressing plate is provided on the other surface through a buffer layer.
