Amplification of higher-order modes by stimulated Raman scattering in H₂-filled hollow-core photonic crystal fiber

Abstract

We report a method for amplifying higher-order guided modes, synthesized with a spatial light modulator, in a hydrogen-filled hollow-core photonic crystal fiber. The gain mechanism is intermodal stimulated Raman scattering, a pump laser source in the fundamental mode providing amplification for weak higher-order seed modes at the Stokes frequency. The gain for higher-order modes up to ${\mathrm{LP}}_{31}$ is calculated and verified experimentally.
