摘要：

Photonic crystal slab consisting of square lattice of Si nanopillars sandwiched between two low-refractive-index silver layers was fabricated. Transmittance spectra (TE polarization and [01] direction of the lattice) displaying clear photonic band gap (PBG) dip were obtained. Missing row and reduced diameter row linear defects were introduced into the lattice. Transmittance studies of this system for TE polarization suggest that both linear defects can work as reduced-index waveguides, a spectral feature assigned to the guided mode supported by the missing row being observed.
