Green’s function for photonic crystal slabs
Physical Review E, 2005Green's tensors for photonic crystal (PC) slabs are numerically solved by the coupled-dipole approximation (CDA) technique. The obtained components of Green's tensors satisfy discontinuous or continuous conditions at interfaces of scatterers. This shows that the CDA technique is very applicable to studying the properties of PC slabs.

Half-disordered photonic crystal slabs
Applied Optics, 2016Optical transmission spectra of finite-thickness slabs of two-dimensional triangular-lattice photonic crystals of air holes in a dielectric matrix with various concentrations of randomly located vacancies (absent air holes) are studied. We focus on structures in which only one half of the structure-the incidence or transmission side-is disordered.

Control of exceptional points in photonic crystal slabs
Optics Letters, 2017Various ways of controlling the extent of the ring of exceptional points in photonic crystal slabs are investigated. The extent of the ring in photonic crystal slabs is found to vary with the thickness of the slab. This enables recovery of Dirac cones in open, non-Hermitian systems, such as a photonic crystal slab. In this case, all three bands exhibit

Slab polymer photonic crystals
SPIE Proceedings, 2004Photonic crystals enable a reduction in the size of current photonic devices by virtue of forbidden propagation, except along engineered lines of defects. Furthermore, propagation above the band-gap has unique characteristics such as the superprism effect.

Plasmon polaritons in a metallic photonic crystal slab
physica status solidi (c), 2003We study the transmission properties of metallic nanowire arrays on dielectric waveguide substrates. The optical response of these metallic photonic crystal slabs is strongly affected by the coupling between their photonic (waveguide mode) and electronic (localized particle plasmon) resonances. A large Rabi splitting of 240 meV is found in transmission

Slow-Light Trapping in a Photonic Crystal Slab
2007 Conference on Lasers and Electro-Optics (CLEO), 2007We present a general scheme to trap slow-light in a photonic crystal slab and achieve high Q/V ratio with a fabrication tolerant design, well suited for low-threshold microlasers and cavity quantum electrodynamics.

Scattering at sidewall roughness in photonic crystal slabs
Optics Letters, 2003We have simulated the effect of sidewall roughness in photonic-crystallike structures with different vertical refractive-index contrast. We treated the scattering off a sidewall irregularity as a radiating dipole excited by the incident waveguide mode.

Direct observation of photonic modes in photonic crystal slabs
2008 10th Anniversary International Conference on Transparent Optical Networks, 2008Guided-mode resonances at the gamma-point are characterized via normal-incidence transmission measurements through photonic crystal slabs. By placing the photonic crystal slab between two orthogonally oriented polarization filters, direct light transmission is suppressed.

Characterization of photonic bands in metal photonic crystal slabs
Optics Communications, 2014Abstract By rotating metal photonic crystal (PC) slab around ΓK and ΓM lattice directions, transmission spectra were measured to study photonic bands in such metal PC with a triangular lattice. We found that the photonic band diagram for the ΓM lattice direction is different from that for the ΓK direction.

The radiational eigenmodes in photonic crystal slabs are classified into guided and leaky modes. The former are genuine eigenmodes with infinite lifetimes, while the latter are quasi-eigenmodes with finite lifetimes. We will show that the dispersion curves of photonic crystal slabs are well represented by the folding of those in uniform dielectric ...
