Lattice-mismatch Moire laser with strong flatband coupling
Donghwee Kim, Chiwon Shin, Changi Kim +5
Inter-cell and/or interlayer coupling in Moire superlattices can generate flatbands and collective eigenmodes that enable emergent physical phenomena, motivating extensive explorat…
Transverse Magnetic Mode Laser in Photonic Crystal Nanobeam Cavity
Taesu Ryu, Hwi-Min Kim, Sang-Woo Ki +2
We first experimentally demonstrated a transverse magnetic (TM) mode laser in a Photonic crystal (PhC) slab structure at room temperature. This study proposes a PhC nanobeam (NB) c…
Evolution of topological edge modes from honeycomb photonic crystals to triangular-lattice photonic crystals
Jin-Kyu Yang, Yongsop Hwang, Sang Soon Oh
The presence of topological edge modes at the interface of two perturbed honeycomb photonic crystals with symmetry is often attributed to the different signs of Berry curvatu…
Photonic Band Gaps in 3D Network Structures with Short-range Order
Seng Fatt Liew, Jin-Kyu Yang, Heeso Noh +4
We present a systematic study of photonic band gaps (PBGs) in three-dimensional (3D) photonic amorphous structures (PAS) with short-range order. From calculations of the density of…
Lasing in localized modes of a slow light photonic crystal waveguide
Jin-Kyu Yang, Heeso Noh, Michael J. Rooks +3
We demonstrate lasing in GaAs photonic crystal waveguides with InAs quantum dots as gain medium. Structural disorder is present due to fabrication imperfection and causes multiple…
Photonic Band Gap Effects in Two-dimensional Polycrystalline and Amorphous Structures
Jin-Kyu Yang, Carl F. Schreck, Heeso Noh +4
We study numerically the density of optical states (DOS) in two-dimensional photonic structures with short-range positional order, and observe a clear transition from polycrystalli…
