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…

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…

Exceptional point induced unidirectional radiation from non-Hermitian plasmonic structures
Yuto Moritake, Masaya Notomi
Non-Hermitian (NH) photonics has attracted considerable attention from researchers owing to exotic properties that originate from the parity-time () phase transition…
