Broadband Dispersion Compensation of Single Mode Fiber by using Modified Decagonal Photonic Crystal Fiber having High Birefringence
摘要： This paper presents a highly birefringent dispersion compensating microstructure modified decagonal photonic crystal fiber for broadband transmission communication system. According to simulation, negative dispersion coefficient of ?610 ps/(nm.km) and a relative dispersion slope (RDS) close to that of single mode fiber of about 0.0036 nm-1 with birefringence of the order 2.1×10-2 was obtained at 1550 nm. The variation of structural parameters is also studied to evaluate the tolerance of the fabrication. Moreover, effective area, residual dispersion, effective dispersion, confinement loss, and nonlinear coefficient of the proposed modified decagonal photonic crystal fiber (M-DPCF) are also mentioned and discussed.

Applied magnetic field effect on core mode properties of MFPCF
摘要： The work investigates a magnetic ?uid ?lled photonic crystal ?bre (MFPCF) at 1557 nm under applied magnetic ?eld. They computed the refractive index change of the MF due to the magnetic ?eld and used it in simulations to ?nd the effective refractive indices of the core and the ?rst cladding modes of the MFPCF. Then, they analytically computed the effective mode area and the con?nement loss. The effective refraction index of the core mode increasing by 0.0341% under the applied ?eld of 0–500 Oe, increases the effective mode area by 128% and the con?nement loss by 866%. Thus, a rather small change in the effective refractive index gives rise to a rather large change in con?nement loss. However, this effect saturates after about 500 Oe because the MF nanoparticles no longer change their magnetic orientation. It is also noteworthy that the con?nement loss changes almost linearly with the effective area as the magnetic ?eld change. These results suggest that MFPCF are suitable for a tunable attenuator and a ?eld sensor.
