Chalcogenide embedded quasi photonic crystal fiber for nonlinear optical applications

Abstract
In this article, a new quasi photonic crystal fiber (PCF) with chalcogenide ellipse core has been proposed. Fundamental optical transmission characteristics such as effective area, confinement loss, numerical aperture (NA), nonlinearity and power fraction has been investigated through the full vector finite element method (FV-FEM). The proposed model shows ultra low confinement loss of 2.08 × 10−5 dB/m, significant NA of 1.2 × 10−8 dB/km and effective area of 1.42 × 10–12m2 in x-polarization mode. This shows a high nonlinearity of 4.72 × 104 W−1km−1. This raised model may play a vital role to sensing, biomedical imaging, fluorescence monitoring and optical signal processing and nonlinear applications.
