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…
Non-Bloch band theory of generalized eigenvalue problems
Kazuki Yokomizo, Taiki Yoda, Yuto Ashida
Waves in a variety of fields in physics, such as mechanics, optics, spintronics, and nonlinear systems, obey generalized eigenvalue equations. To study non-Hermitian physics of tho…
High Transmission in 120-degree Sharp Bends of Inversion-symmetric and Inversion-asymmetric Photonic Crystal Waveguides
Wei Dai, Taiki Yoda, Yuto Moritake +3
Bending loss is one of the serious problems for constructing nanophotonic integrated circuits. Recently, many works reported that valley photonic crystals (VPhCs) enable significan…
Optical non-Hermitian skin effect in two-dimensional uniform media
Taiki Yoda, Yuto Moritake, Kenta Takata +3
The non-Hermitian skin effect (NHSE) is a novel localization phenomenon in certain non-Hermitian systems with gain and/or loss. Most of previous works study the non-Hermitian skin…
