▎ 摘　　要

NOVELTY - Graphite alkene-micro-nano fiber composite structure full-light modulator, relating to light communication and sensor transmission technology area. Including magnesium fluoride substrate, micro-nano fibre, graphene film, the micro-nano fibre comprising input optical fiber, output optical fiber, the input optical fiber, output optical fiber respectively fixed on the magnesium fluoride substrate above, between input optical fiber, output optical fiber interval, graphene thin film cover on input optical fiber, output optical fiber of the input optical fiber, output joint terminal of optical fiber separately set on the magnesium fluoride substrate out. Work length equal the full light modulator volume small, response speed is fast, preparation technology is simple, no need to waveguide fiber coupled, package is easy, low cost, facilitate full optical fiber, wide light band (cover visible light and near infrared wave band) is. The full-light modulator use of graphite alkene drawing cone optical fiber structure, system error and light loss and very small.
