摘要： A method of producing an elliptic core type polarization-maintaining optical fiber comprises the steps of providing a glass rod comprising a cladding glass layer around the periphery of a core glass layer, the cladding glass layer having a softening point higher than the softening point of the core glass layer, removing two side surface portions of the glass rod by machining along the axial direction of the glass rod to form a machined rod noncircular in cross section, outside depositing fine silica glass particles on the periphery of the machined rod, followed by sintering to provide a support glass layer having a softening point higher than the softening point of the cladding glass layer, and drawing the thus obtained glass rod body as an optical fiber preform. Since the portion for constituting the core of the optical fiber is formed by machining, the core is permitted to have a high ellipticity. An optical fiber with the desired size and birefringence index is obtained by regulating the conditions of production.

摘要： The fiber-optic rotation sensor comprises a sensing loop using an optical fiber which essentially performs a single polarization when bent, both end portions of the sensing loop being disposed with the principal axes of polarization thereof orthogonal to each other and the end portions being joined by an evanescent wave coupling to form a ring interferometer, a device for introducing to an input end of the interferometer a linearly polarized light at a bearing of 45.degree. relative to the principal axis of polarization of the interferometer, and a retardation measuring system provided at an output end of the interferometer for picking up an electrical output proportional to a rotational angular velocity applied to the interferometer. When the linearly-polarized light is introduced to the input end of the coupling portion of the ring interferometer at a bearing of 45.degree. with respect to the principal axis of polarization of the interferometer, the light is branched into two polarized light beams running through the sensing loop, one clockwise and the other counterclockwise. The polarized light beams are recombined with each other to be input to the retardation measuring system from which an electrical output proportional to the rotational angular velocity applied to the interferometer is picked up.

摘要： A core waveguide having a substantially rectangular cross section, with the width thereof greater than the thickness thereof, is provided in a cladding formed on a substrate, and a rare earth element-doped layer is provided in the core waveguide along the waveguiding direction of the waveguide. With the width of the core waveguide set greater than the thickness of the core waveguide, good optical confinement in the width direction of the waveguide is obtained, which enables light to be absorbed by the rare earth element-doped layer efficiently and concentratedly. It is thereby possible to achieve a marked improvement in the excitation efficiency of excitation power. Thus, an enhanced excitation efficiency is achieved with less addition of a rare earth element, and a high-gain optical amplification waveguide free of concentration extinction is provided.

摘要： A process for producing cooper foil laminated plates using rolled copper foils made of oxygen-free copper is described. The major feature of the present process is that in laminating a rolled copper foil on an insulating substrate, the rolled copper foil is ground or abraded and immediately brought into contact with water or steam to form a hydrate layer on the surface thereof. This hydrate layer increases the adhesion strength of the rolled copper foil to the insulating substrate through an adhesive, producing a copper foil laminated plate having an adhesion strength sufficiently high for practical use. Thus these copper foil laminated plates are very suitable for use in wiring of electronic devices.
