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…
On-chip room-temperature CW lasing from a III-V nanowire integrated with a Si photonic crystal platform
Masato Takiguchi, Takuro Fujii, Hisashi Sumikura +3
We report the demonstration of continuous-wave (CW) lasing at room temperature from a III-V semiconductor nanowire integrated into a Si photonic crystal (PhC) cavity. Conventional…
