We proposed and fabricated a terahertz resonant-tunneling-diode oscillator integrated with two offset slot-ring antennas for high-output power and high-directivity radiation. In this device, the length of the antenna, approximately half the wavelength of the oscillation frequency, enables efficient terahertz radiation. The increased radiation conductance, resulting from the offset and the two slot-ring antennas, enables higher output power. Additionally, radiation directivity can be improved by using two slot-ring antennas. The fabricated device generated high-power oscillation of 1.29 mW at 412 GHz. This is the highest output power of a single electronic device oscillator in the 400 GHz range.

具有两个偏置馈电槽环天线的太赫兹谐振隧道二极管振荡器

我们提出并制造了一种集成了两个偏置槽环天线的太赫兹谐振隧道二极管振荡器，用于高输出功率和高方向性辐射。在该设备中，天线的长度约为振荡频率波长的一半，可实现高效的太赫兹辐射。由于偏移和两个槽环天线而增加的辐射电导可实现更高的输出功率。此外，可以通过使用两个槽环天线来改善辐射方向性。所制造的器件在 412 GHz 下产生 1.29 mW 的高功率振荡。这是 400 GHz 范围内单个电子设备振荡器的最高输出功率。
