Abstract

The engineering of specialty lasers with unconventional mode structures is one of the modern challenges in the development of integrated coherent sources. Examples include the use of bound states in the continuum, microlasers with orbital angular momentum, Dirac-band lasers, and topological lasers. In this work, we engineer a two-dimensional lattice of coupled micropillars with lasing line modes. We use a convenient combination of orbital photonic modes to design photonic bands that are flat in one direction and dispersive in the perpendicular one, giving rise to line lasing modes. Such an architecture opens the possibility of implementing densely packed lasing matrices in compact two-dimensional lattices.
