Patent ID: 7965440

Claim:
A device for generating or receiving electromagnetic radiation in a frequency range from 10 GHz to 100 THz, comprising: a housing; a wave guide fiber leading into the housing, the wave guide fiber being adapted for guiding pulsed light having a first central wavelength; a terahertz converter provided in the housing for generating or receiving the electromagnetic radiation in the frequency range from 10 GHz to 100 THz, the terahertz converter being rotatable relative to the housing around an optical axis of the light impinging on the terahertz converter; and a frequency converter for converting the frequency of the light exiting from the wave guide fiber to a second central wavelength, the frequency converter being arranged in the housing between an end of the wave guide fiber and the terahertz converter in such a way that the terahertz converter is impinged upon by the frequency converted light.
