Abstract: 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).

Abstract: 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.

Abstract: The invention provides improved methods for reducing polarization mode dispersion (PMD) in single mode fiber by spinning the fiber during the drawing process in accordance with a spin function having sufficient harmonic content to achieve low levels of PMD for commercial fibers for which the beat lengths of the fibers, including the beat lengths of different portions of the fibers, are variable and thus not readily known in advance. The spin functions of the invention take advantage of certain resonances in energy transfer between polarization modes to achieve substantial reductions in PMD for a wide range of beat lengths. Examples of suitable spin functions include frequency-modulated and amplitude-modulated sine waves.

Abstract: 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.
