The optical conductivity of a new material - graphene 1D-composite are investigated for the development of a new type of optical nanoantenna element base. Studies were hold by the quantum model of nanodetector. The object of research was the composite structure formed by two types of graphene nanoribbons of armchair type A-7 (seven atoms are arranged on a line perpendicular to the line of extended edge) and single-walled carbon nanotube zigzag (10,0), which is covalently bonded with both ribbons. The study has found that the 1D-composite comprising the thin tube (10,0) with a diameter of 0,8 nm provides a high conductivity in the IR and UV ranges, as well as at the frequency of visible light red boundary of 1,6 eV (387 THz).
