Patent ID: 7898348

Claim:
A terahertz oscillation device comprising: a semiconductor substrate; a first electrode placed on the semiconductor substrate; an insulating layer placed on the first electrode; a second electrode which is placed via the insulating layer toward the first electrode, and opposes the first electrode to be placed on the semiconductor substrate; a MIM reflector formed between the first electrode and the second electrode by sandwiching the insulating layer; a resonator which is adjoining of the MIM reflector and is placed between the first electrode and the second electrode which oppose on the semiconductor substrate; an active element placed at the substantially central part of the resonator; a waveguide which is adjoining of the resonator and is placed between the first electrode and the second electrode which oppose on the semiconductor substrate; and a horn apertural area which is adjoining of the waveguide and is placed between the first electrode and the second electrode which oppose on the semiconductor substrate.
