Robust lasing modes in coupled colloidal quantum dot microdisk pairs using a non-Hermitian exceptional point
Pairs of microdisk lasers are one of the most common systems for studying optical PT-symmetry. Here, Lafalce, Zeng et al. study the influence of fabrication imperfections in a disk pair made from colloidal quantum dots and show that the resulting three modes also coalesce at an exceptional point.
