Modulation instability induced supercontinuum generation in Barium Zinc Borate glass doped with Praseodymium based photonic crystal fiber

In this work, we propose a novel Barium Zinc Borate glass doped with Praseodymium (BZBP) based photonic crystal fiber (PCF) as a potential candidate for supercontinuum generation. We focused on the increased nonlinearity of the proposed PCF because of high nonlinear refractive index of BZBP. To demonstrate the supercontinuum generation, we have considered one of the important nonlinear phenomena called modulation instability, which leads to pulse breaking and generation of ultrashort pulses along with broad spectra. The proposed BZBP based PCF can be used to achieve ultrabroad spectra within short propagation distance by using a pulse of large pulse width and low peak power.
