Origins and conservation of topological polarization defects in resonant photonic-crystal diffraction
Xuefan Yin, Takuya Inoue, Chao Peng +1
We present a continuative definition of topological charge to depict the polarization defects on any resonant diffraction orders in photonic crystal slab regardless they are radiat…
Demonstration of high-power photonic-crystal surface-emitting lasers with 1-kHz-class intrinsic linewidths
Ryohei Morita, Takuya Inoue, Masahiro Yoshida +4
Photonic-crystal surface-emitting lasers (PCSELs) are capable of single-mode, high-power lasing over a large resonator area owing to two-dimensional resonance at a singularity poin…
Unidirectional perfect reflection and radiation in double-lattice photonic crystals
Takuya Inoue, Naoya Noguchi, Masahiro Yoshida +3
Non-Hermitian photonic systems are known to exhibit unique phenomena, where non-Hermiticity is typically introduced by material loss or gain. Here, we propose and experimentally de…
Topological unidirectional guided resonances emerged from interband coupling
Xuefan Yin, Takuya Inoue, Chao Peng +1
Unidirectional guided resonances (UGRs) are optical modes in photonic crystal (PhC) slabs that radiate towards one side without the need for mirrors on the other, represented from…
