Abstract: A low latency free-space optical data communication channel has at least two opposing parabolic mirrors for transmitting an optical communication signal in the form of a parallel beam across a free-space channel. The input and output of the collimators are multicore optical fibers. Multiple cores of the multicore optical fibers are positioned at the focal points of the at least two opposing parabolic mirrors and the at least two opposing parabolic mirrors image the optical communications signal in each core of the multiple cores of the multicore fibers into corresponding cores of opposing multicore fibers forming at least one optical communication channel.

Abstract: The present invention generally concerns the use of Bragg optical fibers in chirped pulse amplification systems for the production of high-pulse-energy ultrashort optical pulses. A gas-core Bragg optical fiber waveguide can be advantageously used in such systems to stretch the duration of pulses so that they can be amplified, and/or Bragg fibers can be used to compress optical signals into much shorter duration pulses after they have been amplified. Bragg fibers can also function as near-zero-dispersion delay lines in amplifier sections.

Abstract: Included among the many structures described herein are photonic bandgap fibers designed to provide a desired dispersion spectrum. Additionally, designs for achieving wide transmission bands and lower transmission loss are also discussed. For example, in some fiber designs, smaller dimensions of high index material in the cladding and large core size provide small flat dispersion over a wide spectral range. In other examples, the thickness of the high index ring-shaped region closest to the core has sufficiently large dimensions to provide negative dispersion or zero dispersion at a desired wavelength. Additionally, low index cladding features distributed along concentric rings or circles may be used for achieving wide bandgaps.
