Ebook: Design and Analysis of Rectangular Core Photonic Crystal Fiber for Supercontinuum Generation

A rectangular core photonic crystal fiber design in As2Se3 chalcogenide glass has been reported for mid-infrared supercontinuum generation. The structural parameters have been tailored for all normal dispersion profile. The proposed structure possesses nonlinearity (Υ) as large as 20956 W-1 km-1 at 2800 nm wavelength with very low and flat dispersion of -2.38 ps/(nm×km). We have generated supercontinuum spectra spanning 1480 – 9990 nm using only 4 mm length of proposed photonic crystal fiber pumped with femtosecond optical pulses of peak power of 500 W at 2800 nm. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
