X-band photonic band-gap accelerator structure breakdown experiment
Physical Review Special Topics. Accelerators and Beams, 2011 In order to understand the performance of photonic band-gap (PBG) structures under realistic high gradient, high power, high repetition rate operation, a PBG accelerator structure was designed and tested at X band (11.424 GHz). The structure consisted of

Band gaps and cavity modes in dual phononic and photonic strip waveguides
AIP Advances, 2011 We discuss theoretically the simultaneous existence of phoxonic, i.e., dual phononic and photonic, band gaps in a periodic silicon strip waveguide. The unit-cell of this one-dimensional waveguide contains a hole in the middle and two symmetric stubs on ...

Theoretical investigation of the dynamical and static characteristics of vertical-cavity surface-emitting lasers incorporating two-dimensional photonic crystals [PDF]
, 2006 In this work we present a spatial and dynamical model of a semiconductor vertical-cavity surface-emitting laser (VCSEL) incorporating a spatial built-in optical waveguide created by the defect in a two-dimensional photonic crystal (PC). The PC is created

The Nested Topological Band-Gap Structure for the Periodic Domain Walls in a Photonic Super-Lattice
CrystalsWe study the nested topological band-gap structure of one-dimensional (1D) photonic super-lattices. One cell of the super-lattice is composed of two kinds of photonic crystals (PhCs) with different topologies so that there is a domain wall (DW) state at ...

Photonic Band-Gap Inhibition of Modulational Instabilities [PDF]
Physical Review Letters, 2004 Spatial structures as a result of a modulational instability are studied in a nonlinear cavity with a photonic crystal. The interaction of the modulated refractive index with the nonlinearity inhibits the instability via the creation of a photonic band gap. A novel mechanism of light localization due to defects and pattern inhibition is also described.
