[IEEE 2019 URSI Asia-Pacific Radio Science Conference (AP-RASC) - New Delhi, India (2019.3.9-2019.3.15)] 2019 URSI Asia-Pacific Radio Science Conference (AP-RASC) - Near-field vertical coupling between terahertz photonic crystal waveguides

摘要： We demonstrate near-field coupling between terahertz photonic crystal waveguides in the out-of-plane dimension, with no direct physical contact, by making use of coupled-line techniques. Efficient transfer (i.e. ≈ 80%) of terahertz power from one waveguide to another is experimentally achieved. Thereafter, multi-Gbps data is successfully transmitted via this near-field link. This study can be considered a step towards practical connectors between terahertz photonic crystal waveguide circuits.
