Vortex Beam Lasing from III‐V Nanowires Epitaxially Grown on Silicon‐on‐Insulator
Laser &Photonics Reviews, EarlyView.An epitaxially grown InGaAs nanowire photonic crystal laser on silicon‐on‐insulator is demonstrated to emit vortex beams carrying orbital angular momentum. Deforming the honeycomb lattice causes the band inversion effect and creates symmetry‐protected bound states in the continuum, enabling single‐mode lasing with a topological charge of −2 ...
