Terahertz-wave beam control by photonics technology

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We introduce our developing photonics-based technologies for THz-wave generation/combination by arrayed photomixers. We demonstrated THz-wave power combination and beam steering at 300 GHz with phase tuning at optical delay lines. In addition, we made electrically-controlled arrayed phase shifters on a silica-based planar lightwave circuit, which showed a high-speed beam steering with 1-kHz repetition. For a future integrated THz-wave source, we also designed and fabricated arrayed lightwave sources to be coupled to the arrayed photomixers. Combination of these two arrays would enable to generate THz wave only with DC currents or voltages.
