Low loss switchable topological photonic crystal enabled by submicron-scale patterning and phase-change of Sb2Se3
Takahiro Uemura, Yuto Moritake, Eiichi Kuramochi +3
Photonic topological insulators (PTIs) offer robust platforms for light manipulation, but reconfigurable control of their topological properties without degrading performance remai…
Observation of non-Hermitian point gap in photonic crystals
Yuto Moritake, Nozomi Ogawa, Issei Takeda +7
Non-Hermitian point gap (NHPG) is a unique phenomenon in non-Hermitian systems and induces non-Hermitian skin effect (NHSE). In photonic crystals, NHPG and the NHSE have previously…
Chiral Diffraction from Aperiodic Monotile Lattice
Yuto Moritake, Masato Takiguchi, Takuma Aihara +1
Aperiodic systems such as quasiperiodic systems exhibit unique properties different from periodic structures. In 2023, Smith et al. discovered a new aperiodic structure: a single-s…
Propagation and circulating modes of reciprocal non-Hermitian skin effect
Issei Takeda, Taiki Yoda, Yuto Moritake +2
The non-Hermitian skin effect (NHSE) is a novel localization phenomenon, in which all bulk states in a non-Hermitian system under certain conditions are localized at the edge of th…
