摘要

Abstract

Exceptional point (EP) is a special degeneracy of n

on-Hermitian systems. One-dimensional transmission systems operating at EPs are widely studied and applied to chiral conversion and sensing. Lately

two-dimensional systems at EPs have been exploited for their exotic scattering features

yet so far been limited to only the non-visible waveband. Here

we report a universal paradigm for achieving a high-efficiency EP in the visible by leveraging interlayer loss to accurately control the interplay between the lossy structure and scattering lightwaves. A bilayer framework is demonstrated to reflect back the incident light from the left side (|

−1

0.999) and absorb the incident light from the right side (|

–4

). As a proof of concept

a bilayer metasurface is demonstrated to reflect and absorb the incident light with experimental efficiencies of 88% and 85%

respectively

at 532 nm. Our results open the way for a new class of nanoscale devices and power up new opportunities for EP physics.
