Abstract
The determination of lasing mode within quantum cascade (QC) photonic crystal (PC) microcavity laser was analyzed. The lasing mode symmetry was determined by position of nodal lines within micro-bolometer camera measurements of polarized spatial distribution. The group theory categorized eigenmodes of given electromagnetic system according to its spatial symmetries. The results show that reduction of far-field emission pattern symmetry was due to subtle near-field asymmetries.
