On-chip terahertz Goubau-line waveguides with integrated photoconductive emitters and mode-discriminating detectors
We have measured the picosecond time-domain response of Goubau-line waveguides, formed on quartz substrates, by integrating regions of low-temperature-grown gallium arsenide into the waveguides toExpand
