Topological Edge and Corner States in Biphenylene Photonic Crystal
Huyen Thanh Phan, Keiki Koizumi, Feng Liu +1
The biphenylene network (BPN) has a unique two-dimensional atomic structure, where hexagonal unit cells are arranged on a square lattice. Inspired by such a BPN structure, we desig…

Microwave hinge states in a simple-cubic-lattice photonic crystal insulator
Shun Takahashi, Yuya Ashida, Huyen Thanh Phan +4
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 cu…
