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…
Towards optimization of photonic-crystal surface-emitting lasers via quantum annealing
Takuya Inoue, Yuya Seki, Shu Tanaka +3
Photonic-crystal surface-emitting lasers (PCSELs), which utilize a two-dimensional (2D) optical resonance inside a photonic crystal for lasing, feature various outstanding function…
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…
Integrated near-field thermophotovoltaic device overcoming far-field blackbody limit
Takuya Inoue, Keisuke Ikeda, Bongshik Song +4
Near-field thermal radiation transfer overcoming the far-field blackbody limit has attracted significant attention in recent years owing to its potential for drastically increasing…
High-efficiency thermophotovoltaic system that employs an emitter based on a silicon rod-type photonic crystal
Masahiro Suemitsu, Takashi Asano, Takuya Inoue +1
Thermophotovoltaic systems in principle enable utilization of heat that is usually regarded as wasted energy. However, the wavelength selectivity of the thermal emitter required fo…
Spin pumping into two-dimensional electron systems
Takuya Inoue, Gerrit E. W. Bauer, Kentaro Nomura
We study the spin current injected by spin pumping into single layer graphene and the two-dimensional electron gas (2DEG) with ferromagnetic contacts using scattering theory. The s…
