Designing of highly birefringence, dispersion shifted decagonal photonic crystal fiber with low confinement loss

In this article we propose a decagonal photonic crystal fiber (D-PCF) consisting unique cladding without structural complexity having very high birefringent of the order of 10(-2), less effective area of few square microns as well as low confinement loss of the order of 10(-2) dB/m at 1.55 pm wavelength. The zero dispersion wavelength is also achieved in the near infrared region. This study clearly attributes to the fact that the zero dispersion wavelength at the near infrared region, very high birefringence and low confinement loss can be adjusted according to the necessity by changing the structural parameters with considerable fabrication tolerance. This fiber can prove itself useful in laser technology, telecommunication, non-linear application, sensor technology and also in making polarization maintaining devices. (C) 2017 Elsevier B.V.
