Analysis of bending effects on hexagonal and rectangular photonic crystal fiber

This paper presents photonic crystal fibers (PCF)based on hexagonal and rectangular structures designed to be operated in a range of wavelength 1.3 to 1.7µm and effects of various parameters on bending loss of the different structured index guiding PCFs have been investigated. According to simulation, bending loss is reduced down to 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−12</sup> dB/km from 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−5</sup> dB/km by changing bending radius and core diameters.Due to having low bending loss, these PCF structures can be used in applicationsof optical technologies including telecommunication and sensing applications.
