项目摘要

Toward realization of high-capacity wireless communications in the undeveloped terahertz frequency region, we investigated oscillation and modulation of terahertz waves, and wireless data transmission. For the oscillation device, we achieved room-temperature oscillation at 1.55 THz using resonant tunneling diodes with reduced electron delay, which is the highest frequency of semiconductor electron devices. High-power oscillation and high-speed direct modulation of these oscillators were achieved with the structure optimization of the integrated micro-antennas. Modulators for terahertz waves with optical signal and transistors with high current drivability for modulation were also obtained. Wireless data transmission was demonstrated with the resonant- tunneling-diode transmitter and Schottky-barrier-diode receiver, and feasibility of high-capacity communication was obtained.

为了在未开发的太赫兹频段实现高容量的无线通信，我们研究了太赫兹波的振荡和调制，以及无线数据传输。对于振荡器件，我们使用共振隧穿二极管实现了1.55THz的室温振荡，降低了电子延迟，这是半导体电子器件中最高的频率。通过对集成微天线的结构优化，实现了这些振荡器的高功率振荡和高速直接调制。还得到了具有光信号的太赫兹波调制器和可用于调制的大电流驱动晶体管。利用共振隧穿二极管发射机和肖特基势垒二极管接收机进行了无线数据传输，得出了实现大容量通信的可行性。
