Non-Centrosymmetric -Phase GaS Nanobelts for On-Chip Nonlinear Photonic Applications
Yukihiro Endo, Masato Takiguchi, Yoshiaki Sekine +2
Second-order nonlinear optical processes in van der Waals (vdW) semiconductors offer a compelling route toward compact, integrable photon-conversion platforms. Among III-VI vdW sem…
Inverse-Designed Non-Hermitian Hollow Nanowire Cavity for Generating Optical Orbital Angular Momentum
Xuen Zhen Lim, Masato Takiguchi, Ryuji Kuruma +2
We designed a gallium nitride hexagonal hollow nanowire whispering gallery mode cavity that generates an |m|=6 topological light with orbital angular momentum (OAM). OAM is generat…
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…
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…
Vector beam generation from standing hollow GaN nanowire lasers on sapphire substrate
Masato Takiguchi, Sylvain Sergent, Benjamin Damilano +9
We fabricated GaN based hollow nanowires standing upright on a sapphire substrate by the sublimation method and found that they exhibit laser oscillation at room temperature. These…
Emulating the local Kuramoto model with an injection-locked photonic crystal laser array
Naotomo Takemura, Kenta Takata, Masato Takiguchi +1
The Kuramoto model is a mathematical model for describing the collective synchronization phenomena of coupled oscillators. We theoretically demonstrate that an array of coupled pho…
