▎ 摘　　要

NOVELTY - The modulator has a dielectric isolation layer arranged between a first graphene strip (5) and a second graphene strip (6). The first graphene strip is connected with a first electrode (71). The first electrode is arranged between a first ground electrode (81) and a second ground electrode (82). The second graphene strip is connected with a second electrode (72). The second electrode is arranged between a third ground electrode (83) and a fourth ground electrode (84). A surface of a substrate layer (1) is divided into two parts. USE - Graphene based strip- shaped light waveguide travelling wave absorption type light modulator. ADVANTAGE - The modulator improves modulation bandwidth and light modulation rate. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene based strip-shaped light waveguide travelling wave absorption type light modulator. ubstrate layer (1) Graphene strips (5,6) Electrodes (71,72) Ground electrodes (81,82,83,84)
