摘要

我们证明了光子带图中的特殊点导致光栅耦合器投射出恒定强度的自由空间光束。我们的发现为投射具有无衰减轮廓的空间宽自由空间光束铺平了道路。

Exceptional Points in Photonic Grating Band Diagrams Lead to Decay-Free Radiation

We demonstrate that exceptional points in a photonic band diagram lead to constant-intensity free-space beams projected from grating couplers. Our findings pave the way for projecting spatially broad free-space beams with decay-free profiles.
