摘要:

金属狭缝阵列透镜是一种通过激发和操控表面等离子体激元,突破衍射极限,实现光束调控的纳米光子器件。如何快速、高效地设计具有一定功能的金属狭缝阵列,并且在不影响器件功能的前提下,增大狭缝尺寸,使器件便于加工,是该类器件走向实际应用的关键问题。本文提出一种可以实现光束调控的新的金属狭缝阵列透镜的设计方法,将金属狭缝阵列作成几何曲面结构,可快速、高效地设计透镜,实现光束的调控作用。该方法设计的透镜,金属狭缝尺寸在80 nm,便于设计之后的加工制备,将加速纳米光子器件的实用化。

Abstract:

The optical lens of metallic nano-slits array is a kind of nano optical device, which can break through the diffraction limit and control the beam. It is a key problem of this kind of devices to practical application, to design the metallic nano-slits array with a certain function fast, efficient and with large nano-slits size which can be facilitate to process. In this paper, a new kind of method is presented to design the metallic nano-slits array, which can control the beam. It is to design the geometric surface of the structure, which can fast, efficient design the lens. The lens we have designed with large nano-slit, 80 nm, can be facilitate to process. It will accelerate the practical application of nano photonic devices.
