摘要： An integrated optical circuit having a turning mirror formed by an end surface of a planar waveguide forms a turning mirror deflector surface. More specifically, the integrated optical circuit includes a planar optical waveguide formed within a cladding layer wherein the planar waveguide has a deflector end surface positioned adjacent to a region, such as a gap. The refractive indices of the planar waveguide and region are in a ratio of no less than approximately 1.3 to provide a desired refractive index discontinuity. This refractive index discontinuity in combination with the positioning of the deflector end surface at an angle relative to an axis extending perpendicular to the direction of the waveguide in the range of 24.degree. and 67.degree. enables an advantageous deflection of an optical signal.

摘要： An optical fiber waveguide is disclosed wherein germanium dioxide (GeO.sub.2) and phosphorus pentoxide (P.sub.2 O.sub.5) are radially graded in the core of the optical fiber for the purpose of achieving minimum modal dispersion over a broad range of wavelengths. The phosphorus pentoxide has its maximum concentration on the axis of the fiber core and is graded to zero concentration at the core-cladding interface. The germanium dioxide has its maximum concentration at the core-cladding interface, is constant throughout the cladding and is graded to zero concentration on the axis of the fiber core. The ratio of maximum P.sub.2 O.sub.5 to maximum GeO.sub.2 is approximately 11.6 and therefore the numerical aperture is only slightly degraded as a result of the reverse doping of germanium dioxide.

摘要： A method and apparatus are disclosed for coupling a multimode laser to a multimode fiber using a multimode tapered structure. The disclosed multimode tapered structure accepts an optical beam having a highly elliptical beam shape and converts the optical beam for acceptance by the circular multimode optical fiber. According to one aspect of the invention, the multimode tapered structure has a tapered form having an elliptical cross section at one end to match the rectangular laser aperture, and a circular cross section at the other end to match the fiber core. The disclosed multimode tapered structure is tapered from a smaller dimension at the input end that matches the dimension of the multimode light source to a larger dimension at the output end that matches the circular core of the multimode fiber. Depending on the selection of the numerical aperture and the length of the multimode tapered structure, coupling efficiencies up to 98 percent may be achieved with the present invention.

摘要： A low-rate data transmission system and method are disclosed that use the Faraday effect to modulate the polarization state of light traveling in an optical fiber. The resulting change in polarization is used to communicate information over the fiber. The low-rate data transmission system includes a low-rate signal source producing current in a wire coil wrapped around an optical fiber. Information is conveyed in accordance with the present invention by the selectively introducing a polarization change into the light carried by the fiber. Generally, the source light at the input of the optical fiber can be randomly polarized and information is conveyed in accordance with the present invention by the presence or absence of a predefined polarization introduced into the light. The longitudinal magnetic field produced by a current in the coil rotates the plane of polarization of the light, in accordance with the well-known Faraday effect. When the current in the coil is modulated by the signal source, the resulting change in polarization communicates information over the fiber.

摘要： A method for controlling a bore diameter of an optical fiber ferrule is disclosed. The diameter of the bore is controlled by collapsing the ferrule around a rod inserted in an over-sized bore formed therein. The diameter of the rod is selected to match the diameter of the optical fiber to be supported by the ferrule. Thus, after the rod is subsequently immersed in liquid nitrogen removed from the ferrule, the ferrule has a bore diameter which is defined by the diameter of the rod. Suitable materials for the ferrule and the rod include glass and metal, respectively.

摘要： An exemplary embodiment of an acousto-optic planar waveguide modulator includes a planar waveguide structure with an input section connected to a multimode section connected to an output section. The input and output sections have structures for propagating an optical signal in a first transmission mode. The multimode section has a structure in which an optical signal can propagate in the first transmission mode and a second transmission mode. A surface acoustic wave source is used to direct a surface acoustic wave at the multimode waveguide section to cause a periodic change in the refractive index for coupling optical signal energy between the even and odd transmission modes. As a consequence, power of an optical signal propagating in the even transmission mode is transferred to the odd transmission mode. This power transfer causes an attenuation of the optical signal propagating in the even transmission mode from the multimode section to the output section. Such attenuation can be varied in accordance with a second signal to modulate the optical signal by correspondingly varying the surface acoustic wave energy to produce a modulated optical signal. Further embodiments modulate optical signals propagating in single mode waveguides having their transmission modes evanescent field coupled to respective transmission modes of the planar multimode waveguides.

摘要： A mechanically stable self-aligned M.times.N optical switch having a low insertion loss is achieved by employing three cleaved silica optical structures containing a plurality of waveguides. A monolithic silica optical structure is cleaved into the three corresponding structures. Each of the first and third structures has a cleaved edge and a respective set of waveguides extending parallel to a corresponding structure surface. The second structure has two substantially parallel cleaved edges and a plurality of sets of waveguides extending parallel to a corresponding structure surface. The corresponding surfaces of the first, second and third structures are positioned on, for example, surfaces of respective first, second and third bases aligned in a common plane. The structures are further positioned with the cleaved edges of the second structure arranged adjacent to and facing respective ones of the cleaved edges of the first and third structures. In operation, the second structure is moveable in a direction along the cleaved edges relative to the first and third structures to selectively align different waveguide sets with the waveguides of the first and third structures to provide various different optical connections between the waveguide sets of the first and third structures.
