Abstract:
1. Device for analyzing a sample using radiation in the terahertz frequency range, comprising: a transmitter comprising a THz signal generator for generating an electromagnetic THz signal, the THz signal generator comprising a nonlinear transmission line; a surface plasmon polariton generating unit adapted to convert the THz signal into a surface plasmon polariton; a THz surface plasmon polariton sensor adapted for bringing generated surface plasmon polaritons in interaction with a sample; and a receiver comprising a THz surface plasmon polariton detector adapted for converting surface plasmon polaritons into an electromagnetic THz signal; the transmitter, the surface plasmon polariton generating unit, and the receiver being either integrated on one common substrate or on two separate substrates; wherein all components for generating THz surface plasmon polaritons are integrated on said substrate or substrates, respectively.
