    "abstract": "We present the design of mid-infrared and THz quantum cascade laser cavities\nformed from planar photonic crystals with a complete in-plane photonic bandgap.\nThe design is based on a honeycomb lattice, and achieves a full in-plane\nphotonic gap for transverse-magnetic polarized light while preserving a\nconnected pattern for efficient electrical injection. Candidate defects modes\nfor lasing are identified. This lattice is then used as a model system to\ndemonstrate a novel effect: under certain conditions - that are typically\nsatisfied in the THz range - a complete photonic gap can be obtained by the\nsole patterning of the top metal contact. This possibility greatly reduces the\nrequired fabrication complexity and avoids potential damage of the\nsemiconductor active region.",
