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： An athermalized integrated optical waveguide device in which thermal spectral shifts are inhibited is provided and in which the light transmitting properties are insensitive to temperature variations and fluctuations. The athermnalized integrated optical waveguide device has at least two waveguide core arms, preferably comprised of a silica glass, with the core arms cladded with a waveguide cladding composition, preferably a silica glass that has a boron concentration different than the cores. The first waveguide arm and the second waveguide arm have a difference in an effective index thermal slope in order to provide an athermalized device such as an intereferometer on a substantially planar substrate. In addition the at least two waveguide core arms are comprised of path segments having different waveguide core dimensions.

摘要： 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.

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.

摘要： A method of modifying programs and databases having abbreviated date fields to achieve year 2000 compliancy includes examining an original database to ascertain the location of date fields, creating a supplementary PALM file that includes fully expanded date fields representative of corresponding date fields in the original database and modifying instructions or modules of the original program to access the PALM file for date information instead of the original database. The PALM file contains fully expanded date representations of abbreviated date fields of the original database. The PALM file also includes record identifiers and field identifiers to enable the modified program to access the required date information. Portions of the program requiring modification are identified by scanning for keywords that are generated from an examination of the database and/or from field layout definitions. The program is also examined for related keyword constructs or redefinitions found in the program itself. When converted, the modified program accesses the PALM file for date processing and accesses the original database for other processing steps. Further, a representative database having expanded date entries may be created based on examining a sample of an original database, and used by a modified legacy program to attain year 2000 compliancy.

摘要： A hydrolyzing flame technique is used to build up glass soots of at least two different compositions upon a rotating starting member. The process is repeated until the soots define at least one helically-oriented body of soot of one composition completely enveloped by a soot of a second composition. The soot-covered starting member is then subjected to heat to fuse it whereupon the soots are fused into compositions exhibiting different indices of refraction. The member can then be drawn into a elongate structure comprising an optical waveguide extending helically through the body of the structure.
