Abstract
We have succeeded in fabricating a two-dimensional photonic band structure with a near-infrared band gap for p-polarization in a two-dimensional Brillouin zone.The sample consists of circular air rods constituting a triangular lattice with a lattice constant of 1.17 µm and a background dielectric constant of 2.6. The transmission spectra were measured over a range from 1.4 to 5.0 µm for both p- and s-polarizations. The energies of complete reflection regions observed in the Γ- X direction were in good agreement with the theoretical calculation for both p- and s-polarizations. This agreement indicates that the above band gap should exist.Keywords
