This is a review on theoretical and experimental studies on dielectric microcavities, which
play a significant role in fundamental and applied research. The basic concepts and theories …

Metal-based negative refractive-index materials have been extensively studied in the
microwave region. However, negative-index metamaterials have not been realized at near …

A review of the properties of silicon-based two-dimensional (2D) photonic crystals is given,
essentially infinite 2D photonic crystals made from macroporous silicon and photonic crystal …

Nanotechnology, science, and engineering spearhead the 21st century revolution that is
leading to fundamental breakthroughs in the way materials, devices, and systems are …

We present an analysis of the optical structure of a representative diatom, Coscinodiscus
granii. The silica cell wall can be regarded as a photonic crystal slab waveguide with …

We report on the first experimental evidence of negative refraction at telecommunication
wavelengths by a two-dimensional photonic crystal field. Samples were fabricated by …

A novel design for realizing all optical analog to digital converter will be proposed in this
paper. The proposed structure consists of two main parts; a nonlinear 3-channel …

We numerically demonstrate a metamaterial with both negative ε and negative μ over an
overlap** near-infrared wavelength range resulting in a low loss negative-index material …

In this paper, we used the novel defective resonant cavities to design an eight-channel
photonic crystal demultiplexer. We showed that by choosing appropriate values for the width …

Metamaterials with negative permittivities or/and permeabilities greatly enrich photonic
bandgap (PBG) engineering in one-dimensional (1-D) photonic crystals (PhCs) …
