A manufacturing method of a device for generating terahertz radiation includes forming a distributed feedback laser epitaxy module; etching the distribution feedback laser epitaxy module corresponding to a first window to a predetermined depth; forming an indium gallium arsenide epitaxy layer above the distributed feedback laser epitaxy module corresponding to the first window; etching out the indium gallium arsenide epitaxy layer corresponding to a second window to expose the distributed feedback epitaxy module corresponding to the second window; forming a first electrode, a grating, and an antenna above an upper surface of the distributed feedback laser epitaxy module, an upper surface of the indium gallium arsenide epitaxy layer, and the distributed feedback laser epitaxy module corresponding to the second window, respectively; forming a second electrode above a lower surface of the distributed feedback laser epitaxy module; and forming two metal wires between the grating and the antenna.
