Abstract

Analogous to radio- and microwave antennas, optical nanoantennas are devices that receive and emit radiation at optical frequencies. Until recently, the realization of electrically driven optical antennas was an outstanding challenge in nanophotonics. In this review we discuss and analyze recent reports in which quantum tunneling—specifically inelastic electron tunneling—is harnessed as a means to convert electrical energy into photons, mediated by optical antennas. To aid this analysis we introduce the fundamentals of optical antennas and inelastic electron tunneling. Our discussion is focused on recent progress in the field and on future directions and opportunities.

量子隧穿驱动的光学天线:关键问题综述
与无线电和微波天线类似,光学纳米天线是接收和发射光频率辐射的装置。直到最近,实现电驱动的光学天线是纳米光子学中的一个突出挑战。在这篇综述中,我们讨论和分析了最近的报道,其中量子隧道-特别是非弹性电子隧道-被利用作为一种将电能转换成光子的手段,由光学天线介导。为了便于分析,我们介绍了光学天线和非弹性电子隧穿的基本原理。我们的讨论集中在该领域的最新进展以及未来的方向和机会。
