Abstract: PROBLEM TO BE SOLVED: To obtain an optical fiber improved in the adhesive force between the glass and a photocurable coating film. SOLUTION: This composition comprises a photocurable or electron beam- curable composition and a setting agent, being useful for producing coated optical fibers; wherein the setting agent bears an alkoxysilane functional group bound via the long main chain to the reactive group copolymerizable with the photocurable or electron beam-curable composition; the alkoxy-substituted organosilane group-contg. compound is conjugatedly bound to a relatively long molecule having (meth)acrylate functional group; as part of the photocurable coating material, the long chain raises the adhesive force of the coating material to a glass substrate through conjugatedly binding a high-molecular network texture to the glass substrate.

Abstract: PROBLEM TO BE SOLVED: To obtain an optical fiber coated with coating having a high modulus of elasticity and high heat characteristics for easy removal from the optical fiber by applying protective coating having the room temperature modulus of elasticity of a specific value and high temperature release layer resistance of below specific % of the room temperature release layer resistance. SOLUTION: A preform is supplied to a furnace and as the preform passes the furnace, a glass fiber 12 is drawn from a molten material. After the glass fiber 12 is drawn from the molten material, two layers of the protective coating systems consisting of a radiation curing high-polymer material are applied to the glass fiber 12. The inside layer 14 comes into contact with the glass fiber 12 at the boundary 13 between the glass and the coating and is called as a primary coating. The outer layer 15 is called as the secondary coating and encloses the inner layer 14. The primary coating of the high-polymer material has the on-site modulus of elasticity within a range from 9 to 500 psi at 20 deg.C and has the first release layer resistance at 20 deg.C and the second release layer resistance at a temperature within a range of 100 to 2000 deg.C below 40% of the first release layer resistance.

Abstract: PROBLEM TO BE SOLVED: To measure the volume change of a liquid with consistency by confining a layer of a liquid with consistency in a part of a rigid body, applying a physical or chemical process, and measuring a linear deviation on the surface to be formed. SOLUTION: A layer of consistency liquid 101 is confined in a vessel 104 of a rigid body 100. After the consistency liquid layer comprising a flat surface is confined in the vessel 104, a probe is equilibrated on a layer of the consistency liquid 101. Normally the prove is equilibrated on the surface of layer of the consistency liquid 101 so that the axis at a tip end is vertical to the surface of consistency liquid layer under a force about 10 mg or less. After equilibrium, the thickness of a consistency liquid layer is acquired and the thickness is acquired relative to the bottom surface of vessel. After the thickness of consistency liquid layer is acquired, the consistency liquid is at least partially allowed to react by an arbitrary method such as exposure to light, heat, etc. As reacted, the surface of consistency liquid layer and the probe tip end contacting it are deviated in the direction vertical to the layer surface. The deviation is a measurement for linear deviation as the consistency liquid react. Then the voluminal change of a consistency liquid which partially reacted is acquired as a function of a linear deviation for the consistency liquid layer.

Abstract: PROBLEM TO BE SOLVED: To provide an improved fiber which eliminates clad mode loss in a fiber Bragg grating. SOLUTION: An optical fiber Bragg grating of this invention has a glass optical fiber of a certain length with a core, a Bragg grating formed along the core, a glass cladding layer and a polymer coating which covers the cladding layer and has a refractive index matched with that of the cladding layer. By this matching, clad mode loss can be reduced to 1/4 of the current level, The preferred material of the coating is fluorinated urethane acrylate.

Abstract: PROBLEM TO BE SOLVED: To obtain an optical fiber diffraction grating clad which is intensified in the sensitivity of material for the purpose of a reconstitution characteristic by arranging plural heating elements, generating a temperature gradient along the length of diffraction gratings, and chirping the diffraction gratings. SOLUTION: The device 9 has an optical fiber 11 of a certain length having a series of the optical diffraction gratings 12 having refractive index perturbation 13 and plural heating elements 10 along the diffraction gratings 12. The optical fiber 11 usually has a central core 14, an external cladding 15 and an external coating 16 of the temperature sensing material. The heating elements 10 are made of resistant metals for correcting the diffraction gratings 12 by local heating. When operating, the electric signals impressed to the heating elements 10 establish the temperature gradient at the coating along the diffraction gratings 12, thereby changing the refractive index of the coating. This change effectively chirps the diffraction gratings 12. The heating elements 10 are arranged at uniform intervals and are capable of establishing the desirable gradient by changing the effective heating capacity (for example, the number of coils) thereof.

Abstract: PROBLEM TO BE SOLVED: To make it possible to manufacture an optical fiber having a high- polymer clad of a low refractive index by forming the clads of a curing material consisting of high-viscosity bifunctional or multifunctional (meth)acrylate and a photopolymn. initiator. SOLUTION: This optical fiber consists of a core 10, the first clad (inner clad) 11 and the second high-polymer coating or clad (outer clad) 12. Both of the core 10 and the first clad 11 are formed of silica glass. The second high- polymer coating (outer clad) 12 forms a boundary 13 between the first clad 11 and the second coating. The second high-polymer coating (outer clad) 12 may be composed of a curing compsn. Namely, the optical fiber consists of the core 10 consisting of glass and the clad 12 consisting of the material having the refractive index smaller than the refractive index of the core 10. The clad 12 is formed of the curing material composed of the high-viscosity bifunctional or multifunctional (meth)acrylate and the photopolymn. initiator.

Abstract: PROBLEM TO BE SOLVED: To obtain a method capable of monitoring a multiple wavelength optical system without using costly elements, such as detector arrays and an apparatus therefor. SOLUTION: The physical parameters of the intra-fiber gratings for coupling the light used in the wavelength division multiplex(WDM) optical fiber system between the spatially different mode are scanned, i.e., changed. The space modes are separated by using a mode discrimination device(MDD) 47 and the spectral components separated by the conventional or other suitable detectors 48 are monitored, i.e., detected. The peak wavelength of the coupling the two different modes to each other is changed and the coupling in the fiber optical system is controlled by scanning the intra-fiber gratings. This system uses the long- period gratings for coupling the spatially different modes for propagating the light in the two same direction to each other or the short-period gratings for coupling the mode for propagating the light in a forward direction and the mode for propagating the light in the opposite direction spatially different therefrom to each other.

Abstract: PROBLEM TO BE SOLVED: To substantially prevent the both of the mutual reaction of optically active monomers and a matrix precursor during hardening and the inhibition of the following polymn. of the monomers by making a matrix polymer and a polymer produced from the polymn. of the one kind of plural optically active monomers compatible with each other. SOLUTION: This optical product is composed of a three-dimensionally crosslinked polymer matrix and one kind of plural optically active monomers and makes at least the one kind optically active monomer contain a part which is substantially independent of the polymer matrix other than a monomer functional group. Then, the matrix polymer and a polymer produced from the polymn. of the one or plural optically active monomers are made compatible with each other. A polymn. reaction carefully considered for the formation of the matrix polymer is, e.g. cationic epoxy polymn. cationic vinyl ether polymn., cationic alkenyl ether polymn. cationic allene ether polymn. or cationic ketene acetal polymn.
