Abstract: Prism-coupling systems and methods for characterizing large depth-of-layer waveguides are disclosed. The systems and methods utilize a coupling prism having a coupling angle α having a maximum coupling angle αmax at which total internal reflection occurs. The prism angle α is in the range 0.81αmax≦α≦0.99αmax. This configuration causes the more spaced-apart lower-order mode lines to move closer together and the more tightly spaced higher-order mode lines to separate. The adjusted mode-line spacing allows for proper sampling at the detector of the otherwise tightly spaced mode lines. The mode-line spacings of the detected mode spectra are then corrected via post-processing. The corrected mode spectra are then processed to obtain at least one characteristic of the waveguide.

Abstract: A substrate for a display article includes: a primary surface; a textured region on at least a portion of the primary surface, the textured region comprising surface features that reflect a random distribution, each of the surface features comprising a perimeter that is parallel to a base-plane extending through a thickness of the substrate below the textured region, wherein the perimeter is elliptical. The textured region can further include (i) one or more higher surfaces residing at a higher mean elevation from the base-plane and (ii) one or more lower surfaces residing at a lower mean elevation from the base-plane that is closer to the base-plane than the higher mean elevation. The higher mean elevation can differ from the lower mean elevation by a distance within a range of 0.05 μm to 0.70 μm.

Abstract: According to one embodiment two-core optical fiber is provided for use in Brillouin distributed fiber sensor applications and systems. The two-core fiber includes a first and second core. Each core is configured to exhibit a Brillouin frequency shift greater than 30 Mhz relative to the other core. Further, each core possesses temperature and strain coefficients that differ from the other core. The cores can be configured to produce Brillouin frequency shift levels of at least 30 Mhz relative to one another. These differences in shift levels may be affected by adjustment of the material compositions, doping concentrations and/or refractive index profiles of each of the cores. These optical fibers may also be used in BOTDR- and BOTDA-based sensor systems and arrangements.
