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 aligning and maintaining the alignment of the transmitting unit and the receiving unit in an optical wireless communication system. The receiving unit includes an optical bundle positioned at the focal point of an objective optic element. The optical bundle is comprised of an array of optical fibers, arranged surrounding the receiving fiber. The receiving unit also includes a number of detectors that measure the optical signal strength on a corresponding fiber in the optical bundle. The array of fibers is used to detect the location of the received signal relative to the receiving optical fiber and to provide feedback to adjust the orientation of the optical bundle to optimize the received signal strength. When misalignment occurs between the received signal and the receiving fiber, some of the incident received signal will be captured by one or more of the outer optical fibers. The amplitude of each of the generated signals are then compared to each other, thereby giving a direction in which to drive the optical bundle back into alignment with the received signal. The present invention provides automatic tracking using the information-carrying optical signal, without the need for a separate laser.

摘要： A free space optical communication system is disclosed whereby a transmit telescope and a receive telescope are aligned such that the point of maximum power of the received light beam is incident upon the optical fiber located at a specific point on the focal plane of the receive telescope. Such incidence is achieved by causing the transmitted beam to diverge by moving the transmit optical fiber to a point in front of the focal plane of the transmit telescope until at least a portion of the beam is incident upon the receive optical fiber. The transmit telescope and/or the receive telescope (or, alternatively, only the respective optical fibers of those telescopes) are then moved such that the point of maximum received power for that degree of divergence is incident upon the receive optical fiber. The transmit optical fiber, in response to received power measurements at the receive telescope, then incrementally moves back toward the focal plane of the transmit telescope thereby reducing the degree of divergence and achieving a greater signal per unit area at the receive telescope. As the divergence is reduced, the position of the either the transmit telescope and/or the receive telescope (or, respectively, the optical fibers) is incrementally adjusted to maximize the received power of the received signal which is incident upon the receive optical fiber for each degree of divergence. By monitoring received signal power this iterative process continues until the transmit and receive telescopes are aligned such that the transmitted beam is focused so as to maximize the received power that is incident upon the receive optical fiber.

摘要： In accordance with the invention, an optical multiplexer includes at least one reconfigurable add-drop unit that can add-drop one channel out of a large set by switching the light path through one of a set of fixed add-drop filters. Reconfiguration is done by switching from the add-drop filter path to a bypass path, changing to a different add-drop filter and then switching back. The phase delay of the bypass path is adjusted to maintain nearly maximum transmission during switching. The selection among add-drop filters is done by sliding an integrated optic chip with the set of add-drop filters between input and output waveguides. The reconfigurable add-drop multiplexer unit is latchable, passive between reconfigurations, and has low intrinsic insertion loss. Plural units in series can add/drop plural channels.

摘要： Measuring and setting techniques for relative component orientations and separations is accomplished by projecting a coherent light beam into one end of a gap formed between facing surfaces of adjacent components. This light beam projection causes a corresponding light ray pattern to be projected out of an opposite end of the gap. The arrangement of light rays in the resulting pattern is indicative of the relative positions of, and distance between, the facing surfaces. Such a projected pattern is used for determining the relative positions between adjacent components, alone, or as feedback for adjusting such component positions to achieve a desired orientation and/or separation distance between the components.

摘要： A method is provided of trimming the optical coupling ratio of an optical coupler to a prescribed value. The optical coupler is formed from a plurality of waveguides which each include a core and cladding. In accordance with the method, an irradiation energy is selected that is absorbed by portions of the waveguides located in a coupling region. A dosage of radiation is applied to the waveguide portions at least sufficient to adjust the optical coupling ratio to the prescribed value. The radiation, which may be absorbed by the cladding and/or the core of the waveguides, causes a change in the refractive index difference between the core and cladding of the waveguides. This change in the refractive index difference will result in a change in the optical coupling ratio of the device.

摘要： Efficient coupling between multimode optical fibers and optical devices, such as optical detectors and light emitting diodes, is realized by means of a coupling arrangement comprising a length of homogeneous glass fiber, terminated by a convex microlens. One end of the glass, whose length is greater than the focal length of the microlens, is fusion-spliced to the multimode fiber. The convex microlens is formed at the other end of the homogeneous glass member.

摘要： The present invention relates to method and apparatus for fabricating multimode optical fiber waveguides having reduced modal dispersion as a result of deliberate enhancement of mode coupling in the waveguide. The axial alignment and/or the diameter of an optical fiber waveguide is varied by means of one or more modulated heat sources, such as, for example, a microflame jet or CO.sub.2 laser, directed against the fiber waveguide. By controlling the modulation of the heat source, the spatial distribution of the geometrical perturbation pattern can be controlled, thereby producing controlled mode coupling in the fiber waveguide.
