| Outline of Final Research Achievements |
We proposed and designed a monolithic integrated terahertz (THz) transceiver using resonant tunneling diodes (RTDs), and investigated fundamental operation principle. We simulated the amplifier gain using electromagnetic simulation of the circuit and measured THz characteristics with THz vector network analyzer. From the simulation, we obtained an amplifier gain of ~2 dB at around 1 THz range using RTDs with 0.4 square micron mesa. We fabricated the 300 GHz device for preliminary experiments. However, the amplification was not obtained because of parasitic oscillation with biasing circuit. THz amplification can be obtained by suppress the parasitic oscillation.
