1. An arrangement for an antenna for generating or receiving terahertz radiation comprising:
a photoactive layer that can be activated by optical radiation in a range of 1200 nm to 1700 nm, inclusive;
a substrate transparent to the optical radiation, and to which the photoactive layer is attached; and
a carrier transparent to the optical radiation, wherein the substrate is attached to the carrier and is arranged between the photoactive layer and the carrier, wherein the substrate and the carrier are made of the same material, wherein a first adhesion-promoting layer is arranged between the photoactive layer and the substrate such that the photoactive layer and the substrate layer are situated flat and flush with each other with the first adhesion-promoting layer therebetween, and wherein the first adhesion-promoting layer has a layer thickness of no more than 5 μm.
