Patent ID: 7884767

Claim:
A terahertz wave oscillation device, comprising: a gain section for generating a terahertz wave having a wavelength of λ; a dielectric section arranged in contact with the gain section; a first conductor section arranged in contact with the dielectric section, the first conductor section having a line shape of a length of λ/2; a second conductor section arranged in contact with the dielectric section, and the gain section sandwiched between the first conductor section and second conductor section, the second conductor section having a flat shape; and a structure arranged in contact with the first conductor section, the structure comprising a conductor and having a height more than λ/4 and less than λ, wherein the dielectric section, the first conductor section and the second conductor section constitute a micro-strip line so as to propagate a terahertz wave generated in the gain section, and wherein the structure is arranged at a position on the first conductor section such that the structure, the gain section and the micro-strip line have matched impedances at the position.
