ELECTROMAGNETIC WAVE GENERATION APPARATUS AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave generation apparatus which is compact and generates a high power terahertz wave. SOLUTION: The electromagnetic wave generation apparatus is provided with: a high resistance silicon substrate 1; a negative electrode 3 which is provided on one of faces of the high resistance silicon substrate 1 and has a photoelectric surface 4; a positive electrode 2 which is provided on the surface of the high resistance silicon substrate 1; a power supply 5 which applies a voltage to between the negative electrode 3 and the positive electrode 2 so that a potential of the positive electrode 2 may become higher than that of the negative electrode 3; and an optical irradiation part which irradiates a time modulated light. The photoelectric surface 4 emits electrons when the light is irradiated, and is placed at a position where the light from the optical irradiation part is irradiated and the emitted electrons reach the positive electrode 2.
