Abstract
An oscillating device includes an oscillating substrate 11 of a non-linear optical crystal and having an incident face 11c where a pump wave 3 and an idler wave 4 are made incident; a first waveguide 24A provided in the oscillating substrate 11 and between the incident face 11c and an interacting part 20 of the pump wave 3 and idler waves 4; and a second waveguide 24B provided in the oscillating substrate 11 and between the incident face 11c and the interacting part 20. The first waveguide 24A guides the pump wave 3 and the second waveguide 24B guides the idler wave 4.
Claims6
A device of 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
- 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.
