    Abstract: A unidirectional and bidirectional optical fiber couplers using polymer optical fibers having mirrors formed within the polymer optical fibers for reflecting optical signals. The mirrors comprise a notch having at least one surface angled with respect to the central axis of the optical fiber for reflecting the optical signal perpendicular to its central axis. A unidirectional embodiment allows input optical signals to be coupled from any combination of input optical fibers and transmitted into any combination of output optical fibers. A bidirectional embodiment allows optical signals from tapping fibers to be reflected in opposite directions along a first, or BUS optical fiber. Another aspect of the present invention is an apparatus and method for controlling the depth of the notch by monitoring residue power through the optical fibers while the notch is being cut.

    Abstract: A modular, high-intensity fiber optic color backlight for color displays wherein light is distributed to the display through side-emitting optical fibers. The optical fibers are ordered into an array of channels, wherein each channel contains a number of optical fibers. Each of the individual channels are separated by reflective channel isolators and each channel preferably carries light of a single color. Light detecting fibers are optionally installed in the module so that intensity data may be collected. Each module includes a mechanical and electrical interconnect so that individual modules may be combined, thereby producing displays of arbitrary size.

    Abstract: A subwavelength-resolution optical imaging device is provided for conveying light having a wavelength .lambda. that is emitted, reflected or transmitted by a sample. The device comprises a coherent fiber bundle, which itself comprises a plurality of optical fibers disposed substantially coaxially along their lengths. Each optical fiber also comprises a core having an index of refraction n.sub.1 and a cladding having an index of refraction n.sub.2 thereby providing a value .DELTA., where: ##EQU1## Light is effectively confined within the core of each fiber without need for a separate coating applied to the fibers by selecting the values of n.sub.1 and n.sub.2 for each optical fiber so as to provide a value for .DELTA. which permits at least a predetermined fraction of the light launched into each optical fiber at the sampling end of the coherent fiber bundle to be conveyed through the optical fiber to the observation end of the coherent fiber bundle, and which restricts crosstalk between adjacent optical fibers of the coherent fiber bundle to a predetermined level.

    Abstract: A method of synthesizing a hybrid nanomaterial substrate for use in a light emitting structure is provided comprising the steps of: (a) defining one or more light emission characteristics for the light emitting structure; (b) selecting a nanocrystal and a compatible light emitting molecule; and (c) based on the light emission characteristics synthesizing a hybrid nanomaterial substrate by selectively varying the size of the nanocrystals in the substrate, and selectively bonding the light emitting molecules to surfaces of the nanocrystals, thereby synthesizing a nanomaterial structure that is operable to define a single illuminating entity operable upon application of a single excitation energy value to generate light emissions consistent with the light emission characteristics. A novel hybrid nanomaterial is also provided consisting of a nanocrystal-luminescent molecule structure defining a single illuminating entity with light emission affecting structural characteristics that vary across surfaces defined by the nanocrystals based on (a) selective variability of the size of the nanocrystals; and (b) selective variability across the substrate of the concentration of the luminescent molecule bonded to surfaces of the nanocrystals. Upon application to for example a diode comprising the hybrid nanomaterial of a single excitation energy value, the hybrid nanomaterial substrate converts the energy value into light emissions that across the variable substrate generates light emissions in white light range. The hybrid nanomaterial is tunable to achieve desired light emitting characteristics of the light emitting structure.
