    Abstract: A beam steering system having first diffraction gratings, each one being associated with a corresponding one of a first plurality of grating vectors disposed substantially in a first plane. The gratings diffract optical energy from any one of a plurality of input directions of resonance to a corresponding one of a plurality of output directions. Second diffraction gratings are associated with a second plurality of grating vectors disposed substantially in a second plane. Each one of the second gratings diffracts optical energy from any one of a plurality of input directions of resonance to a corresponding one of a plurality of output directions. An arrangement directs a beam of optical energy to a selected one of the first gratings along a selected one of the plurality of input directions for the selected one of the first gratings, selected to provide the corresponding one of the output directions from the first gratings to be substantially equal to a selected one of the plurality of input directions for the selected one of the second gratings, thereby providing a selectable set of beam output directions.

    Abstract: Color-scanning grating-based backlighting includes a color scanning protocol to provide different colors of light in different regions of a plate light guide with an intervening dark region. A color-scanning grating-based backlight includes the plate light guide and a diffraction grating configured to diffractively couple out a portion of a guided light beam as a coupled-out light beam directed away from a plate light guide surface at a predetermined principal angular direction. The backlight further includes a multicolor light source configured to provide the different colors of light to the plate light guide as the guided light beam according to the color scanning protocol. Provided light of a first color in a first region is separated from provided light of a second color in a second region one or both by the intervening dark region and by a light-confining wall of the plate light guide.

    Abstract: An input light pulse Pi, input at a constant incident angle to a transmission-type diffraction grating 20, is dispersed according to the wavelengths to be output at output angles according to the wavelengths, to be reflected by reflecting mirrors 41, 42, and 43 in series, and thereafter, the light rays are input at incident angles according to their wavelengths to the transmission-type diffraction grating 20, to be output at a constant output angle from the transmission-type diffraction grating 20. The optical path for the light rays of respective wavelength components, output at the constant output angle from the transmission-type diffraction grating 20, is folded back by a rectangular prism 40, to be input at a constant incident angle to the transmission-type diffraction grating 20, and the light rays are output at output angles according to their wavelengths, to be reflected by the reflecting mirrors 43, 42, and 41 in series, and are thereafter input at incident angles according to their wavelengths to the transmission-type diffraction grating 20. The light rays, input at the incident angles according to their wavelengths to the transmission-type diffraction grating 20, are coupled by the transmission-type diffraction grating 20, to be output as an output light pulse Po. Thereby, realizing the pulse width conversion device and the optical amplifier system, which are easily downsized.
