Abstract:
1. 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: a supporting body: an oscillating substrate comprising a non-linear optical crystal, said oscillating substrate comprising an upper face, a bottom face and an incident face on which said pump wave is made incident, wherein said electromagnetic wave is oscillated from an interacting part of said pump and idler waves by parametric effect in said oscillating substrate; an adhesive layer adhering said supporting body and said oscillating substrate; and a film for reflecting said electromagnetic wave provided under said interacting part and formed on and covering a surface of said supporting body on the side of said adhesive layer; wherein said adhesive layer has a refractive index with respect to said pump wave lower than that of said oscillating substrate.
