Integrated Microwave-Photonics (iMWP) for Mobile Terahertz Systems

This keynote talk will highlight the generic advantages integrated photonics offers for compact and mobile THz systems, especially for high spectral efficient THz communications as well as for THz imaging and spectroscopy systems. The talk will also focus on some technological challenges involved in integrating THz photonics and electronics. At first, the state of the art in high output power millimeter-wave and terahertz 1.55 urn InP photodiodes (PDs) including waveguide pin-PDs, UTC-PDs, MUTC-PD, and TTR-PDs will be reviewed. Next, novel techniques for interconnecting and packaging high-frequency THz range photodiodes will be presented. This includes novel planar laminate based THz transitions for interconnecting PDs to rectangular waveguides. Also, compact lens-assisted quasi-optical THz transmitter with integrated planar log-periodic toothed antenna and THz PD arrays for optical beam steering will be reported. Finally, key advantages integrated photonics offers for compact THz systems will be discussed by means of developed THz systems. This includes remote THz LO generation, THz communications and THz spectroscopy.
