    "abstract": "The photonic band dispersion and density of states (DOS) are calculated for\nthe three-dimensional (3D) hexagonal structure corresponding to a distributed\nBragg reflector patterned with a 2D triangular lattice of circular holes.\nResults for the Si/SiO$_2$ and GaAs/AlGaAs systems determine the optimal\nparameters for which a gap in the 2D plane occurs and overlaps the 1D gap of\nthe multilayer. The DOS is considerably reduced in correspondence with the\noverlap of 2D and 1D gaps. Also, the local density of states (i.e., the DOS\nweighted with the squared electric field at a given point) has strong\nvariations depending on the position. Both results imply substantial changes of\nspontaneous emission rates and patterns for a local emitter embedded in the\nstructure and make this system attractive for the fabrication of a 3D photonic\ncrystal with controlled radiative properties.",
