摘要： An optical device, such as the switch, for controlling the passage of a light beam into and out of an end face of a waveguide such as a glass fiber includes utilizing either a layer or drop of liquid material to control the light passage. The liquid material can be a layer, which has changeable optical properties, which can occur by applying a magnetic field, heat or electrical field or the material can be a layer of electrolyte material which will precipitate a reflective layer or electrochromic layer in response to an application of an electrical field. In another embodiment, the liquid material may be moved into and out of engagement with the end face to change the reflective nature of the end face and to cause decoupling of light from the end face or block the transmission of light.

摘要： A planar waveguide lens is characterized in that the same is a gradient lens, whereby the refractive index profile transversely to the lens axis extends approximately parabolically. The lens may be constructed to be multi-mode or may be constructed to be single-mode in the spatial direction perpendicular to the lens axis and perpendicular to the axis in which the indicated change of the refractive index profile extends. Grid structures are provided for dividing the light. The grid structures may be permanent, electro-optically produced or acousto-optically produced. For single mode fibers, the grid structures are produced by acoustic surface waves, while for multi-mode fibers, the grid structures are produced by way of acoustical volume waves.

The reflecting surface can be either a separate reflecting device or the facet of the laser. The apparatus includes two members each having an abutting surface with one of the members positioning the waveguide with the coupling optic to lie along an axis perpendicular to the abutting surface and the other member positioning the semiconductor laser with the facet lying in the plane of the abutting surface.

This is accomplished by a skillful selection of the prism angle and the prism material of a single prism or by combining two prisms of different materials whose indices of refraction and prism angles are selected to compensate for the effects of temperature on both the prism and the waveguide. Preferably, the waveguide is doped in a substrate of LiNbO.sub.3 and the prism utilizes a compound prism having a first prism consisting of LiNbO.sub.3 and a second prism of polystyrene.

摘要： An apparatus for manufacturing constrictions in fibers characterized by a stretching device for stretching the fiber and a heating device for brief local heating of the stretched fiber to a softening temperature. To improve the reliability and reproducibility of the constrictions formed in the fiber, the stretching device includes an arrangement which limits the maximum stretching force applied to the fiber and includes two exactly aligned guide grooves, which are spaced apart with the heating means disposed therebetween, for positioning the fiber during the heating and stretching steps. To produce the exactly aligned guide grooves, the method includes providing a substrate having a rectilinear guide groove, securing the substrate on a support member and subsequently removing a center portion of the substrate to leave a pair of spaced substrate sections having the aligned grooves.

摘要： A method for manufacturing a fiber taper with a refractive lens, said method comprising the steps of placing a fiber in an axial tension of a given amount; locally heating a portion of the fiber under tension to cause softening and the formation of a constriction in the fiber in the area of heating; removing the tension and continuing the heating to raise the temperature to a point at which the viscosity of the heated material is such that the surface tension causes a further constriction and a transverse separation of the fiber at the constriction; continuing the heating to form the desired curvature of the lens on the separated ends; and then after the desired curvature is formed, stopping the heating to enable the ends to cool and solidify.
