We attribute the long wavelength limit of the supercontinuum to free-carrier absorption.We acknowledge the support of the International Associated Laboratory in Photonics between France and Australia (LIA ALPhFA), the Agence Nationale de la Recherche (MIRSICOMB, ANR-17-CE24-0028) and the European Research Council (ERC) under the European Union’s Horizon 2020 program (GRAPHICS 648546).application/pdfen-AU© OSA 2021 © 2021 The Author(s)Mid-Infrared Supercontinuum Generation in a Pure Germanium-on-Silicon Ridge Waveguide202110.1364/CLEO_SI.2021.SM3J.42022-08-07
