Proposal for Highly Nonlinear Dispersion-Flattened Octagonal Photonic Crystal Fibers

Polarization maintaining holey fibers for residual dispersion compensation over S + C + L wavelength bands

“…The computational window was surrounded by a PML boundary which is considered to give the most efficient boundary conditions for the HF simulation. Once the modal effective refractive index is obtained by solving an eigenvalue problem drawn from Maxwell equations in FEM, the dispersion D, effective area A eff , confinement loss L c , birefringence B can be obtained using the equations [3] where Re[n eff ] is the real part of effective refractive index n eff , is the wavelength in vacuum, c is the velocity of light in vacuum, E is the electric field amplitude in the medium, k 0 is the free space wave number, Im[n eff ] is the imaginary part of the refractive index, and n x eff and n y eff are the mode indices of the two orthogonal polarization fundamental modes. The material dispersion can be obtained from the three-term Sellmeier's formula and it is directly included in the calculation of chromatic dispersion in Eq.…”

“…They are of great interest as they can have appealing optical properties unavailable in conventional optical fibers [2]. Moreover, HFs offer flexibility in tuning dispersion [3,4] which is crucial in designing dispersion compensating fiber design.…”

“…Recently for the application of sensing and high bit rate communication system lots of research paper are published [1][2][3][4][5][6][7][8][9][10][11]. Birefringence is one of the most interesting characteristics among the features of PCFs.…”

Design of polarization-maintaining photonic crystal fibre for dispersion compensation over the E+S+C+L telecom bands

“…By varying the number and positions of the air-holes, PCFs offer great flexibility in efficiently tuning dispersion [2,3], birefringence [4] and nonlinearity [5,6], which would have been unfeasible with conventional step-index fibres. It is well known that controlling chromatic dispersion and confinement losses are the major issues in the optical fibre communication systems.…”
