| A continuously drawn optical fiber comprising a core and cladding having different refractive indices and forming a single-mode guiding region, and the outer surface of the fiber having a cross-section forming a pair of orthogonal exterior flat surfaces so that the location of the guiding region can be ascertained from the exterior geometry of the fiber, the guiding region being offset from the center of gravity of the transverse cross-section of the fiber and located sufficiently close to at least one of the flat surfaces to allow coupling to a guided wave through that surface by exposure or expansion of the field of the guiding region. | ||||||

| The invention provides a method for making an optical fiber with a uniformly thin section of cladding. A preform having a core and at least one cladding layer is first made. The preform is prepared by cutting the preform so that the core is close to the surface of the preform. An optical fiber is pulled from the cut preform so the core is close to the surface of the optical fiber. The fiber may have cladding further removed by etching. A material selective etch may be used to make a protruding core fiber. Etching may be done on the preform before pulling the fiber. | ||||||

| A method for making mineral fibers comprising discharging molten glass as primary molten streams from orifices and joining at least one primary stream to an adjacent primary stream to form a coalesced stream of different cross-sectional shape from that of the orifices, and hardening the coalesced stream into a glass fiber having a cross-sectional shape similar to the shape of the coalesced stream. | ||||||
| 105 | Method of fabricating high birefringence fibers | US516000 | 1983-07-22 | US4529426A | 1985-07-16 | William Pleibel; Jay R. Simpson; Rogers H. Stolen |
| The present invention relates to a technique for producing polarization-preserving and single polarization optical fibers. As disclosed, high birefringence is introduced into the preform by deforming the fiber preform such that a cladding layer becomes flat and highly conformable, while the core remains hard and substantially round. In particular, a cladding layer with a relatively low melting point is utilized such that when the preform is heated the cladding becomes liquified while the core remains solid. The preform may then be deformed so that the cladding layer is substantially flattened. Standard drawing techniques may then be utilized to form polarization-preserving fibers and single polarization fibers from the preform. | ||||||
| 106 | Stress-induced birefringent single mode optical fiber and a method of fabricating the same | US160698 | 1980-06-18 | US4354736A | 1982-10-19 | Mokhtar S. Maklad; Francis I. Akers; William L. Thomas |
| The stress-induced birefringent single mode optical fiber includes an optical core having a high refractive index and a high thermal expansion coefficient. An arrangement formed from an optical material having a low refractive index and a low thermal expansion coefficient is disposed to engage the outer surface of the core tangentially at opposite ends of a diameter of the core to establish a stress therein. Air encompasses the remainder of the outer surface of the core to provide a light guiding cladding for the core and, hence, the fiber itself. The arrangement to establish the stress may include a pair of flat plates engaging the outer surface of the core tangentially which are entrapped in a circular tube which is concentric with the core such that air is entrapped between the plates and the circular tube to provide the light guiding cladding. Alternatively, an elliptical tube is provided to engage the outer surface of the core at the minor axis of the elliptical tube to provide the desired stress in the fiber. In this case air is enclosed in the elliptical tube to provide the light guiding cladding. | ||||||
| 107 | Single polarization optical fibers and methods of fabrication | US869366 | 1978-01-13 | US4179189A | 1979-12-18 | Ivan P. Kaminow; Vellayan Ramaswamy |
| Orthogonally polarized waves are more effectively decoupled in a waveguide that is fabricated in a manner so as to deliberately enhance stress-induced birefringence. This characteristic is accomplished by introducing a geometrical and material asymmetry in the preform from which the optical fiber is drawn. Three methods of preparing the preform are disclosed. Optical waveguides capable of transmitting power with only one direction of polarization are desirable for use with integrated optical devices which are polarization sensitive. | ||||||
| 108 | Method for the production of one-material optical fibers | US676351 | 1976-04-12 | US4056377A | 1977-11-01 | Franz Auracher |
| A method for producing one-material optical fibers having at least one light conducting component supported in a protective sleeve or casing characterized by forming a one-piece blank having an open cross section by either pressing, continuous casting, chill casting or rolling, working the blank to close the cross section, heating the blank with the closed cross section to a suitable temperature for drawing and drawing the blank with the closed cross section into the one-material optical fiber having a closed cross section. Preferably, the protective casing during the step of forming is formed in two casing components having edges extending along the length of the blank and spaced apart and the step of working the blank forces the edges into engagement with each other to form a closed cross section. | ||||||
| 109 | Method for the production of one-material optical fibers | US676678 | 1976-04-14 | US4046537A | 1977-09-06 | Ulrich Deserno; Franz Auracher |
| A method for the production of single-material optical fibers having a light conducting core supported within a protective sleeve by at least one extremely thin support component characterized by providing a blank having a core and at least one support component disposed within a protective sleeve, heating the blank to a drawing temperature, drawing the blank into a form of an optical fiber and either during the drawing or subsequent thereto, transversely stretching the support component to reduce the ratios of the thickness of the support component to its transverse width and to the thickness of the core of the fiber. In one embodiment of the invention, subsequent to the drawing, a fluid such as a gas under excessive pressure is applied internally to the protective sleeve to expand and inflate the sleeve to transversely stretch the support component. In a second embodiment of the invention, a transverse stretching of the support component is accomplished by asymmetric radial deformation of a circular or noncircular fiber or blank. | ||||||

| An improved polarization preserving birefringent fiber optic member is provided having cross-sectional circular cladding and core members of soft glasses. A metallic coating of an approximately circular configuration, that is offset from the axis of the core and cladding members, is provided with sufficient thickness to provide an anisotropic variation in compressional strain on the core member to create the anisotropy of the refracted index of the core member for preserving polarization characteristics. The optical fiber can be formed by heating a mechanical composite of a core rod and cladding tube, drawing the core and cladding to form a fused fiber and transporting the drawn fiber through a coating bath to provide the variation in thickness. | ||||||
