Electromagnetic wave oscillating devices

Abstract

It is provided 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 includes a supporting body 13, an oscillating substrate 11 of a non-linear optical crystal, an adhesive layer 12 adhering the supporting body 13 and oscillating substrate 11, and a film 15 reflecting the electromagnetic wave formed on a surface of the supporting body 13 on the side of the adhesive layer 12. The oscillating substrate 11 has an upper face, a bottom face and an incident face on which the pump wave is made incident. The adhesive layer 12 has a refractive index with respect to the pump wave lower than that of the oscillating substrate 13.
