Abstract: 【課題】外力を検知する光導波路グレーティングセンサーで、高価な光スペアナを用いないで安価なフォトダイオードで検知することを可能とする光導波路グレーティングセンサーを提供する。【解決手段】片持ち梁に光導波路グレーティングを固定して、測定対象の外力を梁先端部に加えることによって傾斜的に分布した歪みを梁表面に誘起させグレーティングにチャープ機能を持たせる。これに一定波長帯域幅の光信号を入射すれば、反射光の反射スペクトル幅が拡がり、グレーティング内での反射位置は入射口近傍から奥の方へ拡がる。その結果、反射信号光のスペクトルを波長積分した全反射光量は増えることになり、これをフォトダイオードで測定し、外力のセンシングを可能とする。【選択図】図7

Abstract: PROBLEM TO BE SOLVED: To provide a clamp that causes no positional deviation of an optical fiber in the process of forming a fiber grating by irradiating the optical fiber with a ultraviolet laser beam through a phase mask. SOLUTION: In a conventional clamp, an optical fiber is firmly fixed. In this invention, for the purpose of providing the optical fiber with the degree of freedom, it is held through an elastic body comprising a spring and brought into a floating state, making the spring absorb positional deviation due to thermal expansion/contraction of the optical fiber or due to vibration from the outside, so that the position of the fiber grating is always automatically corrected.

Abstract: PROBLEM TO BE SOLVED: To provide a structure of a fiber grating with temperature compensation in which the wavelength fluctuation of the fiber grating caused by change in temperature is suppressed with high accuracy. SOLUTION: A compressive external force imparting structure formed by a combination of materials having a different thermal expansion coefficient is provided in multistages and combined. Compressive external force of a different amount in a different temperature range is applied to a fiber grating, thereby suppressing the wavelength fluctuation of the fiber grating due to change in temperature. To be concrete, a second stage structure is installed in the rear of the compressive external force imparting structure of the first stage that fixes the fiber grating, and the compressive external force is applied by the first stage structure to the fiber grating in a low temperature range while the compressive external force is applied by the second stage structure to the fiber grating through the adjacent first stage structure in a high temperature range by utilizing the elasticity of adhesive resin for fixing the thermal expansion material in the first stage structure. Thus, different temperature compensations are performed in different temperature ranges, thereby suppressing the wavelength fluctuation over the entire desired temperature range.

Abstract: PROBLEM TO BE SOLVED: To provide a method to form a fiber Bragg grating by continuously sublimating, burning and removing and irradiating coated resin with an ultraviolet laser beam without adopting an independent step for removing the coat, which is conventionally adopted in a step for manufacturing the fiber Bragg grating by an irradiation with the ultraviolet laser beam. SOLUTION: When the fiber Bragg grating is manufactured without removing the coated resin by a phase mask method, an optical fiber is arranged close to or in contact with the phase mask and the coating resin is sublimated, burned and scattered, and the mask is contaminated, thus the phase mask can not be reused. In a two luminous flux interference method, the optical fiber is arranged at a position remote from the phase mask and a reflection mirror, these items are not damaged. The fiber Bragg grating is formed by further continuous irradiation with the laser ultraviolet laser beam even after sublimating and burning the coated resin, thus the step for removing the coated resin is dispensed of in the manufacturing step of the fiber Bragg grating.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a fiber grating by irradiation with UV laser light while imparting apodization to the fiber grating. SOLUTION: The method is carried out by use of a two-beam interference device that symmetrically splits UV laser light into two beams using a phase mask, reflects the beams by mirrors symmetrically disposed, and allows the beams to intersect and interference at the position of an optical fiber. First, a first fiber grating is formed, and consecutively the two mirrors are symmetrically rotated at a minute angle to form a second fiber grating as superposing on the first grating, wherein the fiber grating is formed by controlling the mirror rotation angle in such a manner that the phase in the longitudinal direction of the refractive index modulation by the two fiber gratins is identical at the center of the fiber grating and is shifted by 180° shift at the ends.
