“…To obtain large negative dispersion, the radii of the airholes near the core are chosen higher because this affects the dispersion characteristics 17 and to match the RDS to that of single-mode fiber (SMF), the second ring air-hole diameter is scaled down. An artificial defect is created by omitting two air-holes from the first ring that will increase the birefringence.…”

A highly birefringent dispersion compensating microstructure optical fiber (MOF) based on a modified spiral (MS)-MOF is presented that successfully compensates the dispersion covering the E-to L-communication bands ranging from 1370 to 1640 nm. It is shown theoretically that it can obtain a negative dispersion coefficient of about −221 to −424 ps∕ðnm · kmÞ) over S to L bands and −327 ps∕ðnm · kmÞ) at the operating wavelength of 1550 nm. The relative dispersion slope is perfectly matched to that of single-mode fiber of about 0.0036 nm −1 . Besides, the proposed MS-MOF offers high birefringence of 1.79 × 10 −2 with a large nonlinear coefficient of about 41.8 W −1 km −1 at the operating wavelength along with two zero dispersion wavelengths at 610 and 1220 nm. Futhermore, the variation of structural parameters is also studied to evaluate the tolerance of the fabrication.

“…Broadening of optical pulses during propagation along the optical fiber lead to optical pulses to interfere with each other, and this, in turn, results in missing information. Therefore, we need to minimize chromatic dispersion in optical fibers for data transmission .…”

“…In order to design DCFs, the following optical characteristics should be taken into consideration: Both negative dispersion and effective mode area should also be as large as possible, relative dispersion slope (RDS) value should closely match that of the conventional fibers in the third window, and also confinement loss and nonlinear coefficient should be kept to a minimum . Of course, as it is not possible to reach ideal values for the previously mentioned parameters simultaneously, hence a trade‐off must be considered.…”

In this paper, we report the numerical analysis of a nanostructured photonic crystal fiber for making an efficient dispersion‐compensating medium. For our computational studies, the core of the proposed structure is made up of As2Se3, and the cladding structure is a mixture of air holes and holes filled with silica. Our simulations indicate that the chromatic dispersion and the confinement loss at the wavelength of 1.55 µm is −3280 ps/nm/km and 1.71 × 10−6 dB/m respectively. Moreover, the relative dispersion slope at the wavelength of 1.55 µm is computed to be 0.00357 nm−1 that closely matches that of the conventional fibers at the third window. The effect of changing the dimensions of the holes in the first ring and also the distance between the adjacent holes (Λ) in the same ring on chromatic dispersion are also studied. The presented structure is an efficient dispersion‐compensating medium. Copyright © 2016 John Wiley & Sons, Ltd.

“…IG-PCFs are classified as HNL-PCF (having very small core dimensions to provide tight mode confinement), LMA-PCF (having larger dimension of the core and small refractive index contrasts to allow spreading out of the guiding light to provide a larger effective area) and high numerical aperture PCF (HNA-PCF) (having a microstructure cladding surrounded by a ring of air-holes with larger dimensions). Again PCFs are also classified as single mode or multi-mode fibers depending on the number of modes supported by a particular PCF (IG or PBG) as conventional fiber [3][4] [5]. Day by day photonic crystal fibers have increasing its attention because of their attractive properties for examples, very high or very low nonlinearities [4], wideband dispersion ultra-flattened or ultra-low chromatic dispersion [5], lower confinement loss [6], very high or low birefringence [7], endlessly single mode guiding [8], and many others.…”

Design methodology and characteristics analysis of a hexagonal photonic crystal fiber (H-PCF) is presented in this paper. Here, chromatic dispersion, effective area and confinement loss are analyzed for 1.00 to 2.10 μm wavelength range. The PCF is simulated by finite element method (FEM) with perfectly matched layers (PML). Hexagonal PCF with five rings of air holes for near zero ultra-flattened dispersion over 1100 to 1600 nm wavelength range is shown. The special property of proposed PCF is the design simplicity with near zero ultra-flattened dispersion, which is much needed in wavelength division multiplexing (WDM) applications. According to simulation work it is shown that, the designed microstructure optical fiber (MOF) shows near zero ultra-flattened dispersion of 0±1.00 ps/(nm.km), nonlinearity of 12.15 W-1 km-1 and confinement loss less than 10-2 dB/km at the operating wavelength of 1550 nm.
