Title: Antenna designs for near field waveguide coupling between 0.6 – 0.9 THz
Language: English
Abstract:

Dielectric waveguide architectures enable low loss, miniaturized terahertz systems-on-chip with extreme bandwidth. However, transfer of power from active devices to the waveguides presents a severe challenge. In this paper, we present a comparison of two Vivaldi end-fire antenna designs with losses of 2 – 5 dB per coupling interface to silicon waveguides over a frequency range as large as 0.6 – 0.9 THz. We demonstrate lower losses between 0.63 – 0.83 THz as compared to far field in-coupling with silicon lenses, despite being orders of magnitude smaller in size.
