A broadband one-way waveguide is numerically demonstrated at the surface of a 2D magneto-optical photonic crystal containing Yttrium-Iron-Garnet. The strong time-reversal breaking results in the absence of backward-propagating modes and scattering-immune transmission across strong scatters.
In this work, we study the electromagnetic radiation emitted by the propagation of a shock wave through an ionic crystal, NaCl. Our analytical theory and computational experiments predict that under some conditions, weak yet measurable temporally coherent light can be observed emerging from the crystal, typically in the range 1-100 THz. The radiation is generated by an oscillating dipole-like material...
Summary form only given. Photonic crystals can be employed as the substrates of planar antenna to minimize or eliminate the radiation energy loss into the substrate. Previously, surface waves of two-dimensional (2D) photonic crystals has been studied in the case that a complete bandgap exists for only one polarization state. We study the surface waves of a 2D photonic crystal with a complete photonic...
Summary form only given. We propose a class of laser designs based on oneand two-dimensional (1D and 2D) photonic crystals (PCs), which result in surface emitting lasers with a fabrication process similar to that used in edge-emitting distributed feedback lasers. The basic principle employed in our designs is based on our recent discovery that the output coupling characteristics of 2D gratings (or...
