摘要： PROBLEM TO BE SOLVED: To make it possible to efficiently produce an optical fiber cable by immersing one end of a protective tube into a flowable buffer material and imparting a relative positive pressure to the flowable buffer material. SOLUTION: The optical fiber 11 slightly longer than the flexible protective tube 12 is inserted into this tube. The one end of the flexible protective tube 12 is inserted into a pressurized vessel 21 and the one end of the flexible protective tube 12 and the projecting optical fiber 11 are immersed and fixed into the flowable buffer material 13. The other end is inserted into a reduced pressure vessel 31. The space in the pressurized vessel 21 is pressurized and simultaneously the other end of the flexible protective tube 12 in the pressurized vessel 21 is decompressed, by which a pressure difference is generated between both. The flowable buffer material 13 is sucked from the gap between the flexible protective tube 12 and the optical fiber 11. When the flowable buffer material 13 is packed into the entire part of the gap of the flexible protective tube 12 and is then taken out and rested for a while, the packed liquid flowable buffer material 13 changes to the solid buffer material having elasticity.

摘要： PURPOSE: To highly accurately measure current or magnetic field by removing an error due to imbalance in characteristics of a photoelectric transducing element or the like and fluctuation in a reference polarization azimuth of an optical fiber. CONSTITUTION: An optical fiber 4 is provided around a conductor 1 with electricity supplied. Laser light from a semiconductor laser light source 2 for supplying measurement light to the optical fiber 4 is converted into linearly polarized light by a polarizer 3 to be injected. A polarization surface of this light varies in a polarization angle by current I. Emitted light from the optical fiber 4 is separated into p-waves and s-waves by a light detector 5, transduced into a voltage signal by photo diodes 8a, 8b, and separated into AC components and DC components by separating means 11a, 11b. Then, a first component ratio and a second component ratio of the AC and DC components are respectively obtained by subtracting means 12a, 12b, and their product is obtained by a multiplying means 13. A value of the current I is measured from an output from the multiplying means 13.

摘要： PROBLEM TO BE SOLVED: To provide a Faraday rotator the light transmittance of which is improved while reducing its manufacturing cost and to provide an optical isolator.
SOLUTION: The Faraday rotator 1 is manufactured by depositing an antireflection film 3 on two surfaces of a substrate 2 such as glass which are opposed to each other in parallel and depositing a magneto-optical film (for example, a Bi-substituted garnet film) 4 on each of the antireflection films 3 by an aerosol deposition method. An optical element for the polarization-dependent optical isolator is manufactured by arranging the Faraday rotator 1 between two sheets of polarizing glass 5 arranged oppositely so that the polarization axis of one of two sheets is deviated from that of the other by around 45°.

摘要： PROBLEM TO BE SOLVED: To suppress rotation of the plane of polarization due to oscillation of an optical fiber and to reduce the occurrence of birefringence due to an influence of a stress with respect to an optical fiber cable where an optical fiber is protected by a protective tube. SOLUTION: Since an optical fiber 12 is preliminarily aligned with a protective tube 11 and is set, a gap 10a between the optical fiber 12 and the protective tube is uniformly formed. This gap 10a is packed with resin 25. Since resin which is semi-liquefied or solid and causes a stress little to the optical fiber 12 is used as this resin 25 packed in the gap 10a, oscillation of the optical fiber due to the impact from the outside is suppressed as much as possible. Thus, rotation of the plane of polarization is suppressed to perform photometry with a high precision. Since the optical fiber 12 is coated with resin 25, it is strong against the stress, and the occurrence of birefringence is reduced. With respect to this point, photometry is performed with a high precision also.

摘要： PROBLEM TO BE SOLVED: To make high precision current measuring using a simple structure without applying a 45-deg. optical bias. SOLUTION: The light emitted from a light source 1 is segregated into two paths by a fiber coupler 2, and one of the beams is led to an analyzer 10 while the other beam is led to a light receiving element 1. The beam fed to the analyzer 10 is shaped into a linear polarized light, which reciprocates within a sensing fiber 3 to undergo a Faraday rotation. The emitted light from the fiber 3 is separated by the analyzer 10 into a zero-deg. and a 90-deg. polarized component, among which the 90-deg. polarized component is put incident to a light receiving fiber 6. The electric signals sensed from two light receiving elements 7 and 8 are sent to a computing mechanism 20, which performs computation based upon the ratio of the photo intensity measured by the two light receiving elements, and the current flowing through a conductor 4 is determined.
