Abstract: For the first time, a photonic super‐honeycomb lattice (sHCL) is established experimentally by use of a continuous‐wave laser writing technique, and thereby two distinct flatband line states that manifest as noncontractible loop states in an… read more here.

Abstract: Photonic quasi-crystals and photonic crystals with certain degrees of disorder can have a broadband light-matter interaction. In this paper, we present the holographic fabrication of graded photonic super-quasi-crystals through pixel-by-pixel phase pattern engineering using a… read more here.

DOI: 10.3390/photonics8040114
Abstract: It is challenging to realize the complete broadband absorption of near-infrared in thin optical devices. In this paper, we studied high light absorption in two devices: a stack of Au-pattern/insulator/Au-film and a stack of Au-pattern/weakly-absorbing-material/Au-film… read more here.
