Room-temperature continuous-wave topological Dirac-vortex microcavity lasers on silicon
"InAs/InGaAs QD materials monolithically grown... harnessing an auxiliary orbital degree of freedom in topological insulators. By doing so, they were able to control the near-field of the Dirac-vortex cavities to obtain linearly polarized far-field emission... on-chip light source silicon-based photonic integrated circuits... non-Hermiticity, bosonic nonlinearity, and quantum electrodynamics... optoelectronics, communications, and silicon-based PICs with topological robustness"
