THz-WAVE MATERIALS FOR HIGH POWER AND MANUFACTURING METHOD OF THz-WAVE MATERIALS FOR HIGH POWER

摘要

A terahertz wave generating device of high output, a manufacturing method thereof, and a near field electro spinning device are provided to increase an output of the terahertz wave by increasing a voltage applied to a photoconductive antenna based on a wide band gap material with a high breakdown voltage. A terahertz wave generating device of high output includes a semi-insulating substrate and a photoconductive antenna(120). The photoconductive antenna has an electrode pattern formed for applying the voltage to the upper part of the semi-insulating substrate and has an array shape by arranging a wide band gap material in the upper part of the electrode pattern in a row. A lens(110), the photoconductive antenna, and a power supply unit(130) are formed in the upper part of the semi-insulating substrate. A bias voltage is applied from the power supply unit to the photoconductive antenna. If a light wave of an ultraviolet range is injected by a semiconductor laser, the photoconductive antenna absorbs the light and generates the terahertz wave with high intensity.
