The identification of the lasing mode within a quantum cascade photonic crystal microcavity laser emitting at l;8 mm is presented. The symmetry of the lasing mode is determined by the position of nodal lines within micro-bolometer camera measurements of its polarized spatial distribution. Full three-dimensional finite-difference time-domain simulations are also performed, and the resulting vertically emitted radiation field pattern is seen to follow the experimental results closely. © 2004 American Institute of Physics. @DOI: 10.1063/1.1755423#
