Nanocavity Confinement by Orthogonal Valley- and SSH- Topological Interfaces In Glide-Symmetric Photonic Crystal Structures
Takahiro Uemura, Wei Dai, Yuto Moritake +3
Valley photonic crystals enable valley-dependent transport and chirality-selective emission, but incorporating wavelength-scale localization remains challenging. Existing valley-ph…
Transverse spin texture in optical non-Hermitian skin modes
Naoki Ichiji, Issei Takeda, Taiki Yoda +3
In structured electromagnetic fields, polarization textures are often closely linked to the spatial variation of the energy flow. However, this familiar picture has been establishe…
Chiral-Mode Control around a Hermitian Diabolic Point in Discrete Non-Hermitian Coupled Resonators
Kota Yagi, Takahiro Uemura, Yuto Moritake +2
Motivated by the prospect of chiral-mode control in compact photonic systems, we analyze discrete coupled single-mode resonators. Using the minimal three-resonator model, we show t…
Fine Structures of Berry Curvature and Unquantized Valley Chern Numbers in Valley Photonic Crystals
Wei Dai, Taiki Yoda, Yuto Moritake +1
Valley photonics has emerged as a promising platform in topological photonic systems, yet the topological nature of valley-dependent phenomena remains unsettled. Theoretically, int…
