| Outline of Final Research Achievements |
The purpose of this work is to realize the on-chip THz system in which the generation, transmission and detection are electrically driven in a single chip. The platform is in a two-dimensional electron system in strong magnetic field. Using a point-source from quantum Hall edge states and a quantum-dot single photon detector, the following results are obtained. (1) Single photon detection of THz waves propagating a coplanar waveguide (or resonating in a coplanar split ring) is demonstrated. (2) Using these on-chip THz systems, it is found that photon emission due to electrons injected by edge channels requires the spin-flip Landau-level transition, probably through the spin-orbit interaction due to edge drift motion. These results provide the feasibility of on-chip THz photon manipulation and imply the possible applications of photon manipulation due to spin-polarized quantum transport channels.
