    "abstract": "Current quantum cascade lasers based upon conduction band electron\ntransitions are predominantly TM (electrical field normal to the epitaxial\ndirection) polarized. Here we present a study of localized defect modes, with\nthe requisite TM polarization, in connected square and hexagonal lattice\ntwo-dimensional (2D) photonic crystals for application as quantum cascade laser\nresonators. A simple group-theory based analysis is used to produce an\napproximate description of the resonant modes supported by defects situated at\ndifferent high symmetry points within the host photonic lattice. The results of\nthis analysis are compared with 2D finite-difference time-domain (FDTD)\nsimulations, showing a close correspondence between the two analyses, and\npotential applications of the analysis in quantum cascade laser design are\nconsidered.",
