Abstract

Sub-wavelength silica nanowires, are of interest for a range of emerging fiber optic applications since they offer a number of enabling optical and mechanical properties. In particular they allow for sufficient light–matter interactions because of both large evanescent fields outside and strong intensity inside, which are attractive for the integration with 2D materials and enlarging the mechanical and optical nonlinearity, respectively. Here we show its applications in all-optical controlling including a modulator and polarizer based on graphene-integrated helical silica nanowire devices, a delay line based on nanowire Bragg gratings.
