    摘要： Method of producing precision shaped apertures in glass is shown. A hollow glass member defining a longitudinal aperture is provided. A carbon graphite member is shaped externally to a desired shape, disposed within the longitudinal aperture in the glass member, which member is thereafter collapsed about the graphite member taking its shape and size. The graphite member is removed leaving the glass member with a precision aperture therein.

    摘要： Optical fiber structures having at least two cores, whether unitary or separable, may be fabricated by controlling the placement of the cores prior to final processing to make the multi-core fiber structure. When the fiber is to be separable, at least two performs are attached, and the attachment height between adjacent canes is controlled to allow separation to be realized (or attachment to be maintained there between) anywhere along the separable multi-core fiber. These canes are then drawn together to form a desired composite fiber, either or both ends of which may be separated to allow for individual manipulation of fiber ends. The separable multi-core fiber may be utilized to fabricate a dual-port or multi-port optical component in which an input and an output (or multiple input/output) fibers are attached to the component, and the exposed distal ends of the separable multi-core fiber are thereafter separated from one another (even after the entire device is assembled and packaged) to provide separated waveguides for pigtailing or splicing to input or output fibers (or other planar or micro-optic components).

    摘要： An optical fiber and method of making, wherein the optical fiber alternates between regions having different diameters along its length, wherein the refractive index of said blank and the diameters of said fiber are chosen to result in a fiber having alternating regions of positive and negative dispersion at a wavelength which is greater than 1480 nm, yet preferably has a low net dispersion and dispersion slope. A preferred such profile consists of a core region surrounded by a cladding region, said core region comprised of an central core region which is updoped with respect to said cladding region, said central core region surrounded by a moat region which is downdoped with respect to said cladding region, and said moat region is surrounded by an annular ring region which is updoped with respect to said cladding region. In addition, a family of profiles is presented which may be used to produce very low dispersion slope fibers. When used in conjunction with alternating positive and negative dispersion regions, lower net dispersion slope can be achieved. Alternatively, the family of profiles is useful in conventional WDM applications.

    摘要： Disclosed is a fiber optic filter that includes a central core, a ring core concentric with the central core, an inner cladding region of refractive index ni between the central and ring cores, and a cladding layer of refractive index nc surrounding the ring core. The maximum refractive index n1 of the central core and the maximum refractive index n2 of the ring core are greater than nc and ni. The propagation constants of one core mode and one ring mode are different at wavelengths except for at least one wavelength &lgr;O whereby power transfers between the two cores at &lgr;O. At least a portion of the fiber optic filter fiber is wound around a reel to subject it to a continuous curvature, the radius of which determines the amplitude of the attenuation. Such fibers are useful in fiber amplifiers in which the central core contains active dopant ions.

    摘要： Disclosed is a single mode optical waveguide fiber designated for compensating for positive dispersion in optical telecommunications systems. A key characteristic of the invention is that the novel dispersion compensating waveguide, viz., a waveguide having large negative dispersion, contains no dopants, such as fluorine, which lower the refractive index of silica. A refractive index profile design which includes a high refractive index center segment (5) surrounded by a plurality of alternating high (6, 10, 13) and low refractive index segments, provides a dispersion compensation fiber which has the optical properties required for the system to be compensated without sacrificing bend resistance, increasing splicing loss, or elevating polarization mode dispersion.

    摘要： The present invention provides environmentally stable interferometric and lattice devices that exhibit low excess loss and polarization dependent loss. The interferometric and lattice devices of the present invention are inexpensive and simple to make. The modal noise at the splices between the device pigtails and the system fiber is minimized or eliminated. The present invention is an optical device for filtering a light signal. The optical device has a tunable spectral response. The optical device includes an optical fiber having a core region and a cladding with refractive index n2. The first core region includes a core having a refractive index n1 and a first fiber coupling regulator integral with the first optical fiber. The first fiber coupling regulator couples the light signal between a first optical path and second optical path and substantially prevents the light signal from coupling into a third optical path.

    摘要： A fiber optic sensor for simultaneously and independently measuring temperature and axial stress. The fiber sensor includes a pair of polarization-maintaining fibers that have known strain and temperature response curves. Each fiber has a plurality of fiber segments in which the elliptical cores are rotated 45° relative to the preceding core segment. Thus, the phase shift induced by temperature or stress in each of the fibers is detected, and the strain and temperature are derived from the detected phase shift. The fiber optic sensor is capable of dual operation. As both a temperature sensor and an axial stress sensor.
