Supercontinuum generation in high-index doped silica photonic integrated circuits under diverse pumping settings

Abstract

Recent years have witnessed remarkable progress in enhancing the supercontinuum (SC) generation in highly nonlinear photonic integrated waveguides. In this study, we conduct a comprehensive investigation into supercontinuum (SC) generation in high-index doped silica glass integrated waveguides. We explore a variety of femtosecond pumping wavelengths and input polarization states, demonstrating octave-spanning SC bandwidth from visible to mid-infrared wavelengths.
