▎ 摘　　要

NOVELTY - The detector has a transmitting electrode (1), a graphene substrate (2), a light beam splitter (4), a collecting electrode (6), an insulating layer (7) and a substrate electrode (8). The emitting electrode and the collecting electrode are electrically connected with the graphene substrate. The carrier is emitted by the emitting electrode is split by the optical beam splitter after passing through an electronic light momentum selector (3). A three mutually vertical detecting arm is provided to the collecting electrode. The grid of the electronic type light momentum selector and the light beam splitting mirror are set on the vertical upper part of the graphene substrate, the electronic type light momentum selector and the light beam splitter. The insulating layer is provided between the graphene substrate and the substrate electrode. USE - Optical gravitation wave detector for weak signal detection technology field. ADVANTAGE - The wavelength of electron or hole in the light transport of the graphene or the carbon nano-tube is shorter, so that the gravitation wave is more sensitive, the sensitivity of the detector is improved, the size of detector is reduced, and the coordinate orientation information of the force wave source can be obtained by three mutually vertical detecting arms. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the optical gravitation wave detector. 1Transmitting electrode 2Graphene substrate 3Electronic light momentum selector 4Light beam splitter 6Collecting electrode 7Insulating layer 8Substrate electrode
