Outline of Final Research Achievements |
We focused on a photonic crystal slab as technology platform for the integration of terahertz devices, such as planar circuits, with operating frequency located between the radio and light waves. We investigated the low loss of terahertz waveguides using a photonic crystal slab, and achieved a loss of 0.04 dB/cm in the 0.3 THz band. We also demonstrated a compact diplexer using a directional coupler based on photonic crystal waveguides. Then, we fabricated a prototype of a terahertz integrated circuit using the photonic crystal platform for frequency division wireless communication, which consists of the diplexer, a grating coupler as input-output wireless interface, and resonant tunneling diodes. Finally, we discussed the operating bandwidth of terahertz photonic crystal devices.
