Microstructured organic cavities with high-reflective flat reflectors fabricated by using a nanoimprint-bonding process

Autor: Enna, Takuya, Adachi, Yuji, Hirao, Tsukasa, Takahashi, Shun, Yamamoto, Yohei, Yamashita, Kenichi

The integration of photonic microstructure into organic microcavities represents an effective strategy for manipulating eigenstates of cavity or polariton modes. However, well-established fabrication processes for microstructured organic microcavitie

Rashba-Dresselhaus spin-orbit coupling and polarization-coupled luminescence in an organic single crystal microcavity

Autor: Ohkura, Reo, Inukai, Takaya, Takahashi, Shun, Mizuno, Hitoshi, Nakayama, Masaaki, Yamamoto, Yohei, Yamashita, Kenichi

Spin-orbit coupling (SOC) of light plays a fundamental photophysics that is important for various fields such as materials science, optics, and quantum technology, contributing to the elucidation of new physical phenomena and the development of innov

Microwave hinge states in a simple-cubic-lattice photonic crystal insulator

Autor: Takahashi, Shun, Ashida, Yuya, Phan, Huyen Thanh, Yamashita, Kenichi, Ueda, Tetsuya, Wakabayashi, Katsunori, Iwamoto, Satoshi

We numerically and experimentally demonstrated a higher-order topological state in a three-dimensional (3D) photonic crystal (PhC) with a complete photonic bandgap. Two types of cubic lattices were designed with different topological invariants, whic

Polarization superposition of room-temperature polariton condensation

Autor: Moriyama, Yuta, Inukai, Takaya, Hirao, Tsukasa, Ueda, Yusuke, Takahashi, Shun, Yamashita, Kenichi

A methodology for forming a qubit state is essential for quantum applications of room temperature polaritons. While polarization degree of freedom is expected as a possible means for this purpose, the coupling of linearly polarized polariton condense

Elucidation of lasing mechanism in all-inorganic perovskite microcavity with exciton/free-carrier hybrid nature

Autor: Enomoto, Shuki, Ueda, Yusuke, Tagami, Tomoya, Fujiwara, Kentaro, Takahashi, Shun, Yamashita, Kenichi

Lead-halide perovskites are highly promising for various optoelectronic applications including laser devices. However, fundamental photophysics describing the lasing behaviour in this material family have not been investigated systematically, and thu
