چکیده

We present a method for dispersion-tailoring of OmniGuide and other photonic band-gap guided fibers based on weak interactions ("anticrossings") between the core-guided mode and a mode localized in an intentionally introduced defect of the crystal. Because the core mode can be guided in air and the defect mode in a much higher-index material, we are able to obtain dispersion parameters in excess of 500,000 ps/nm-km. Furthermore, because the dispersion is controlled entirely by geometric parameters and not by material dispersion, it is easily tunable by structural choices and fiber-drawing speed. So, for example, we demonstrate how the large dispersion can be made to coincide with a dispersion slope that matches commercial silica fibers to better than 1%, promising efficient compensation. Other parameters are shown to yield dispersion-free transmission in a hollow OmniGuide fiber that also maintains low losses and negligible nonlinearities, with a nondegenerate TE01 mode immune to polarization-mode dispersion (PMD). We present theoretical calculations for a chalcogenide-based material system that has recently been experimentally drawn.

Breaking the glass ceiling: hollow OmniGuide fibers

We argue that OmniGuide fibers, which guide light within a hollow core by concentric multilayer films having the property of omnidirectional reflection, have the potential to lift several physical limitations of silica fibers. We show how the strong confinement in OmniGuide fibers greatly suppresses the properties of the cladding materials: even if highly lossy and nonlinear materials are emplo...

In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting elliptical holes in the first ring of the inner core clad of a dispersion compensating fiber of the hexagonal lattice, increases the wavelength ran...

Novel optical fiber designs for gain flattened optical amplification and dispersion compensation

Optical amplifiers and dispersion compensators form important components of any DWDM system and the overall performance of the system depends critically on the spectral properties of these and other components in the link. This has led to the development of optical amplifiers and fiber based dispersion compensators with specific wavelength dependent characteristics. Dual concentric core fibers ...

Ultrahigh-bit-rate soliton communication systems using dispersion-decreasing fibers and parametric amplifiers.

We study analytically and numerically soliton communication links made by use of dispersion-decreasing fibers and parametric amplif iers. We show that bit rates greater than 100 Gbits/s (one channel, one polarization) can be achieved with large amplif ier spacings (as high as 120 km). The Raman effect and soliton interactions are compensated through optical phase conjugation, whereas fiber loss...
