摘要

我们提出了一种多层二维光学相控阵，能够在没有波长调谐的情况下实现180°× 180°的光束转向范围。通过折射率失配和极端皮肤深度超材料波导，半波长间隔波导之间的倏逝耦合被抑制在−20 dB以下。

Design of 2D Optical Phased Array Emitters with Half-Wavelength Spacing and Less than −20 dB Crosstalk

We propose a multi-layered, 2D optical phased array capable of 180° × 180° beam steering range without wavelength tuning. Evanescent coupling between half-wavelength spaced waveguides is suppressed below −20 dB through index-mismatch and extreme skin-depth metamaterial waveguides.
