Abstract:
1. A device for oscillating an electromagnetic wave having a frequency of 0.1 THz to 3 THz from pump and idler waves by parametric effect, the device comprising: an oscillating substrate comprising a non-linear optical crystal and an incident face on which said pump and idler waves are made incident; a first waveguide provided in said oscillating substrate and between said incident face and an interacting part of said pump and idler waves, said first waveguide guiding said pump wave and further comprising an incident side end and an emitting side end for said pump wave; and a second waveguide provided in said oscillating substrate and between said incident face and said interacting part of said pump and idler waves, said second waveguide guiding said idler wave and further comprising an incident side end and an emitting side end for said idler wave, wherein said pump wave is irradiated from said emitting side end of said first waveguide into said oscillating substrate, wherein said idler wave is irradiated from said emitting side end of said second waveguide into said oscillating substrate, and wherein said pump wave and said idler wave irradiated into said oscillating substrate intersect at said interacting part at a predetermined angle to oscillate said electromagnetic wave.
