Abstract
Disclosed are systems and methods for improving the performance of systems for generating and detecting electromagnetic radiation at terahertz (THz) frequencies. Embodiments of the systems and methods include the fabrication and use of coupling tapers to provide efficient transfer of THz radiation between a photomixer and a waveguide that supports a propagating THz mode. A representative system comprises of a photomixer to convert high-frequency components of an optical pump signal into corresponding electrical THz frequencies, a waveguide that supports a propagating THz mode, and a matching taper that effectively converts the highly localized currents generated by the photomixer to the mode supported by the waveguide.
