    摘要： Apparatus can comprise a light source and a light guide plate. The light guide plate can comprise a plurality of features within an interior of the light guide plate. A feature of the plurality of features can comprise a first refractive index that is different from a refractive index of the light guide plate. A spacing between a pair of adjacent features of the plurality of features can be from about 20 micrometers to about 200 micrometers. The apparatus can be used to direct light out of the light guide plate with a peak radiance oriented from 0° to 30° from a direction normal to the first major surface of the light guide plate. Methods of making the apparatus can comprise emitting a burst of pulses from a laser. Methods can comprise focusing the burst of pulses into a line focus within the light guide plate.

    摘要： The embodiments described herein relate to multi-core optical fiber interconnects which include at least two multi-core optical fibers. The multi-core optical fibers are connected such that the core elements of the first multi-core optical fiber are optically coupled to the core elements of the second multi-core optical fiber thereby forming an array of interconnect core elements extending through the optical fiber interconnect. The multi-core optical fibers are constructed such that cross-talk between adjacent core elements in each multi-core optical fiber is minimized. The multi-core optical fibers are also constructed such that time-delays between the interconnect core elements in the array of interconnect core elements are also minimized.

    摘要： 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.
