摘要

二阶拓扑光子晶体支持偏离传统体边对应关系的局部角模式。然而,跨越光子带隙的角模式的频率偏移还没有实验报告。在这里,我们将平移视为额外的合成维度,从而观察到光子晶体板在参数空间内的无间隙角模。这些角模式在合成平移维度中受到拓扑泵的保护,其存在与具体的角配置无关。我们通过近场扫描测量对无间隙角模式进行了实验成像,并通过全波模拟对其进行了数值验证。我们提出了一种具有梯度平移功能的拓扑彩虹,展示了将光的特定频率成分提取并分离到不同空间位置的能力。我们的工作有助于拓扑光子学的发展,并为探索合成维度的无间隙角模式提供了宝贵的见解。

Observation of gapless corner modes of photonic crystal slabs in synthetic translation dimensions
Second-order topological photonic crystals support localized corner modes that deviate from the conventional bulk-edge correspondence. However, the frequency shift of corner modes spanning the photonic band gap has not been experimentally reported. Here, we observe the gapless corner modes of photonic crystal slabs within a parameter space by considering translation as an additional synthetic dimension. These corner modes, protected by topological pumping in synthetic translation dimensions, are found to exist independently of the specific corner configuration. The gapless corner modes are experimentally imaged via the near-field scanning measurement and validated numerically by full-wave simulations. We propose a topological rainbow with gradient translation, demonstrating the ability to extract and separate specific frequency components of light into different spatial locations. Our work contributes to the advancement of topological photonics and provides valuable insights into the exploration of gapless corner modes in synthetic dimensions.
