Dispersion characteristic of hexagonal and square lattice chalcogenide As2Se3 glass photonic crystal fiber

Original designs of chalcogenide microstuctured optical fibers

“…Numerous simulations and computing studies have shown the high potential of such glassy matrices [37][38][39]. These simulations show that it can be possible to generate light at wavelengths greater than 12 μm in the infrared.…”

Prediction of modal dispersion in nonlinear single mode optical fiber using simple Chebyshev technique

“…(7) and (8) and g(V) in Eqs. (10) and (11) are same as those in [5] but correspond to nonlinear W and (R) obtained by Chebyshev technique used iteratively to compute the relevant nonlinear entities. The entire calculation procedure with results is elucidated in next section and Appendix A.…”

“…Since last few decades, propagation characteristics of conventional and photonic crystal fibers are a topic of keen interest because of their importance in both linear [1][2][3][4][5][6]9,10] and nonlinear [11][12][13][14][15] regimes. Several methods have been reported to calculate the modal dispersion and normalized group delay in nonlinear regime as different propagation behavior has been found in case of nonlinearity.…”

Solid-core square-lattice photonic crystal fibers: comparative studies of the single-mode regime and numerical aperture for circular and square air-holes

“…Tan et al (2009) proposed a SL-PCF with two different airhole diameters in cladding region and found that the PCF proposed gives an ultraflatenned dispersion, which more flat than that of triangular PCF, and the confinement loss as low as about 0.01 dB/ km at wavelength of 1.55 µm. Dabas and Sinha (2010) investigated the dispersion characteristic and the effective area of hexagonal and square lattice chalcogenide As 2 Se 3 glass PCF and observed that only negative dispersion is obtained in wavelength range 1.2-2.5 µm while zero dispersion points are observed in wavelength range 2.5-5 µm for holeto-hole spacing ≥ 2.0 µm for both of the lattices of PCF. Furthermore, they obtained a maximum effective area of about 23 µm 2 for hexagonal and of about 26 µm 2 for square lattice PCF at the wavelength 5 µm using the fiber parameters d/ = 0.9 and = 6 µm.…”
