    Abstract: A light coupler for efficiently utilizing light from a source of optical wave energy in the initiation of light mode propagation in an optical waveguide. The coupler comprises a tapered core of transparent material and a layer of transparent cladding material disposed upon the surface of the tapered core. The refractive index of the core is greater than that of the cladding layer. The core has a large diameter end terminating in an optically polished surface which is adapted to receive light from the light source. The small diameter end of the core is substantially aligned with the core of the optical waveguide.

    Abstract: A method of forming an optical waveguide by first forming a coating of glass with a predetermined index of refraction on the outside peripheral wall surface of a glass cylinder having a different predetermined index of refraction. The glass cylinder and glass coating combination is then heated and drawn to reduce the cross-sectional area and form a clad optical fiber where the core is formed from the glass cylinder and the cladding is formed from the glass coating.

    Abstract: A method of producing a planar optical waveguide by applying to at least a portion of one flat surface of a substantially flat glass substrate having a predetermined desired index of refraction a first coating of glass having an index of refraction greater than that of said glass substrate. Thereafter a second coating of glass having an index of refraction less than that of the first coating of glass is applied over the exposed surface of the first coating of glass. The thickness of the first coating of glass being determined as a function of the highest mode order and the wavelength of light to be propagated within a waveguide having infinite width, and the indices of refraction of the substrate and each of the applied coatings.

    Abstract: OPTICAL WAVEGUIDES INCLUDE A CORE OF DOPED SIO2 AND A CLADDING OF PURE SIO2 OR DOPED SIO2. THE DOPANT, WHICH IS AN OXIDE OF A MULTIVALENT ELEMENT, BECOMES CHEMICALLY REDUCED DURING FABRICATION WHICH USUALLY INCLUDES HEATING THE WAVEGUIDE SO THAT IT CAN BE DRAWN. FOR EXAMPLE, TITANIUM DIOXIDE, A COMMONLY USED DOPANT, HAS TI+4 IONS WHICH ARE REDUCED TO TI+3 IONS DURING THE FABRICATION OF THE WAVEGUIDES. THESE REDUCED IONS INCREASE THE ATTENUATION OF THE WAVEGUIDE. FOR EXAMPLE, REDUCED TITANIUM DIOXIDE IS BROWN. IT ABSORBS LIGHT IN THE BLUE REGION AND THE AMOUNT OF TI+3 IONS IN THE GLASS MUST BE QUITE LOW IN ORDER TO GET THE DESIRED WAVEGUIDE TRANSMISSION PROPERTIES. THE REDUCED MULTIVALENT ELEMENT ION ATTENUATION IS MINIMIZED BY HEAT TREATING THE WAVEGUIDE FIBER AT TEMPERATURES IN THE RANGE OF APPROXIMATELY 800 TO 1,000*C. FOR TIMES OF APPROXIMATELY SIX HOURS OR LESS. THE REDUCED MULTIVALENT ION IS OXIDIZED WITH HYDROXYL IONS DELIBERATELY RETAINED IN THE GLASS AND WHICH SERVE AS THE OXIDIZING AGENT.

    Abstract: A light coupler for transferring optical wave energy to or from an optical waveguide. This coupler comprises a core of transparent material surrounded by a thin layer of transparent cladding material having a thickness less than a few wavelengths. A conically shaped member which surrounds the transparent layer has its base disposed adjacent to the end of the optical waveguide. The refractive index of the transparent layer is lower than that of the core and the conical member. To couple light to the waveguide, a light beam directed at the tapered surface of the conically shaped member is refracted thereby toward the transparent layer where a portion thereof tunnels into the core and is thereafter coupled into the waveguide. When it is utilized as an output coupler, light radiates from the tapered surface at an angle dependent upon the mode of propagation in the waveguide.

    Abstract: Modulation of light in a fused silica optical waveguide is accomplished by a Faraday effect rotation of the plane of polarization of the light propagating in the waveguide. The fused silica waveguide utilized has unique characteristics of low attenuation and low depolarization due to the purity of the fused silica, the manner in which the fused silica is made, the use of the same base material for the core and cladding layer, and a single mode transmission characteristic. The low attenuation and low depolarization permit low strength magnetic fields to cause large rotations of the plane of polarization of the light beam in the waveguide. Because of the length of the light path exposed to the magnetic field, rotations of at least 90* can be accomplished with the application of as little as 100 oersteds of magnetic field along the longitudinal axis of the guide.
