Low-loss multimode optical nanofibers could provide a platform for studying and technologically exploiting nonlinear light-matter interactions. Here, adiabatic transport of multiple modes and highly efficient fundamental-to-fundamental third harmonic generation is demonstrated in a submicron silica fiber.
