This study proposes an optical rectenna that combines a hollow resonator with a metal–insulator–metal (MIM) tunnel diode that is capable of photoelectric conversion (at various visible and infrared wavelengths). It enables the conversion of thermal radiation with different peak wavelengths, such as sunlight and thermal radiation (from heat sources in various temperature ranges), into electric power. The MIM tunnel diode was placed on the wall of a hollow resonator. It rectified the induced current generated by the resonance of the magnetic field. The photoelectric conversion capability of the proposed device applied to visible light is experimentally demonstrated in this study.

空心谐振器与金属-绝缘体-金属隧道二极管耦合的具有宽波长覆盖范围的光学整流天线

这项研究提出了一种光学整流天线，它将空心谐振器与能够进行光电转换（在各种可见光和红外波长下）的金属-绝缘体-金属 (MIM) 隧道二极管结合在一起。它能够将具有不同峰值波长的热辐射，例如太阳光和热辐射（来自不同温度范围的热源）转换为电能。MIM 隧道二极管放置在空心谐振器的壁上。对磁场共振产生的感应电流进行整流。本研究通过实验证明了所提出的适用于可见光的器件的光电转换能力。
