Abstract: To generate high-power, high-directivity terahertz (THz) radiation, in this article, we propose and fabricate a 2-D resonant-tunneling-diode (RTD) THz oscillator array. The array is formed ...

Abstract: Aimed at increasing the yield rate of large-scale vertical-comb-driven tilt-tip (TT) micromirror array (MMA), this paper, for the first time, introduces double-SOI (D-SOI) and our previously ...
