| Abstract | Nonlocal investigations are presented for exciton-photon coupling
in three-dimensional quantum-dot photonic crystals in diamond
lattice. A complete photonic band gap can exist in the diamond
structure. Moreover, the effects of radius of quantum dot and
lattice constant on the photonic band structure are studied. It is
found that the width of the band gap can be broaden by increasing
filling ratio. Furthermore, a special kind of defect, quantum dots
with different radius in a face-center cubic lattice, is studied,
and a profound effect on the band structure is found. |
