Transmission properties of microwaves at an optical Weyl point in a three-dimensional chiral photonic crystal
S. Takahashi, S. Tamaki, K. Yamashita +3
Microwave transmission measurements were performed for a three-dimensional (3D) layer-by-layer chiral photonic crystal (PhC), whose photonic band structure contains 3D singular poi…
Elucidation of lasing mechanism in all-inorganic perovskite microcavity with exciton/free-carrier hybrid nature
Shuki Enomoto, Yusuke Ueda, Tomoya Tagami +3
Lead-halide perovskites are highly promising for various optoelectronic applications including laser devices. However, fundamental photophysics describing the lasing behaviour in t…
Reflectivity of Finite 3D GaAs Photonic Band Gap Crystals
Takeyoshi Tajiri, Shun Takahashi, Cornelis A. M. Harteveld +3
We study the optical reflectivity of three-dimensional (3D) photonic band gap crystals with increasing thickness. The crystals consist of GaAs plates with nanorod arrays that are a…
Circular dichroism in a three-dimensional semiconductor chiral photonic crystal
S. Takahashi, T. Tajiri, Y. Ota +3
Circular dichroism covering the telecommunication band is experimentally demonstrated in a semiconductor-based three-dimensional chiral photonic crystal (PhC). We design a rotation…
Large anisotropy of spin-orbit interaction in a single InAs self-assembled quantum dot
S. Takahashi, R. S. Deacon, K. Yoshida +4
Anisotropy of spin-orbit interaction (SOI) is studied for a single uncapped InAs self-assembled quantum dot (SAQD) holding just a few electrons. The SOI energy is evaluated from an…
