An optimal design of photonic crystal optical fibers for simultaneous dispersion compensation and Raman amplification is investigated by numerical simulation using the finite-difference simultaneous over-relaxation method. The proposed fiber was fabricated and experimental characterization results are presented. Figure 1 Raman gain, ␥, as a function of the pitch parameter, ⌳, for various d/⌳ values. The single star represents the C-band DC-PCF with physical parameters d/⌳ ϭ 0.89 and ⌳ ϭ 0.93 m.ABSTRACT: Refraction of obliquely incident plane waves due to the interface of a vacuous half-space and a half-space occupied by a simply moving, nondissipative, isotropic dielectric-magnetic medium is considered, when the medium's velocity lies parallel to the interface and in the plane of incidence. Counterposition of the refracted wave vector and time-averaged Poynting vector occurs when the medium's velocity is sufficiently large in magnitude and makes an obtuse angle with the incident wave vector. The counterposition induced by relative motion occurs whether the refraction is negative or positive when the medium is at rest.

“…In order to assess this point, the Raman properties of the dispersion-compensating (DC) MOF were first modeled using a procedure similar to that described in Fuochi et al [25] but using the SOR formalism [21] rather than a finite-element approach. The calculated Raman gain as a function of geometrical MOF parameters such as pitch and hole diameter is shown in Figure 2.…”

The design and performance of microstructured optical fibers (MOFs) for simultaneous dispersion compensation and Raman amplification is numerically investigated. We studied a lumped Raman amplifier designed to compensate the signal loss and dispersion introduced by a 100-km, 16-channel C-band WDM link. The impairments induced by the nonlinearities caused by the small mode area of the designed MOF are investigated and the analysis is extended to include non-ideal factors such as excess background losses, splice loss, and the geometry variations 255 256 S. P. N. Cani et al.during the fabrication process. The results are discussed and compared to those obtained for conventional dispersion compensating fibers (DCFs).
