We measure the local near-field spin in topological edge state waveguides that emulate the quantum spin Hall effect. We reveal a highly structured spin density distribution that is not linked to a uni
This paper presents a time and cost-effective method for the large-area fabrication of photonic crystals with nanometerscale features on GaN material. The proposed technique utilizes e-beam lithograph
Study of the solar absorber with photonic crystal or micro structures as the heat absorbing surfaces operated at a high-temperature was conducted. Numerical calculations based on rigorous coupled-wave
