Photonic crystals are periodic dielectric structures having periodicity of the order of the wavelength. Consequently, they offer the ability to control the propagation of electromagnetic waves in a similar way as the periodic potential aspects the electron ...

The ubiquitous role of optical fibres in modern photonic systems has stimulated research to realize slow and fast light devices directly in this close-to-perfect transmission line. Recent progress in developing optically controlled delays in optical fibres ...
The authors address feature-size dependence in Ar/Cl2 chemically assisted ion beam etching (CAIBE) in the context of the fabrication of photonic crystal (PhC) structures. They systematically investigate the influence of various parameters such a ...
The field of photonic crystals is a rapidly developing branch of modern optics. Photonic crystals are believed to be the cornerstone for a wide range of new photonic devices controlling the confinement and propagation of light. These artificial structures ...
We experimentally investigate the effect of residual disorder on the dispersion curve of light near a band edge. A Fourier space imaging technique accurately distinguishes the propagating regime from evanescent regime in planar photonic crystal. (C) 2009 O ...

Feature size dependence in Ar/Cl2 chemically assisted ion beam etching of InP-based photonic crystals (PhCs) and its influence on the optical properties of PhC devices operating in the band gap are investigated. The analysis of the measured quality factors ...
The ubiquitous role occupied by optical fibres in modern photonic systems has steadily stimulated research to realize slow and fast light devices directly in this close-to-perfect transmission line. This potentially offers the key advantage of a direct and ...
The authors report on InGaN microcavity light-emitting diodes with an effective thickness of similar to 450 nm at the emission wavelength of similar to 415 nm. The starting material for the flip-chip laser lift-off device is a structure with an active regi ...

The effect of surface passivation in BCl3/N-2 inductively coupled plasma reactive-ion etching of GaAs-based photonic crystals (PhCs) was investigated. It is shown that sidewall passivation is crucial for achieving cylindrical, vertical PhC holes, where the ...
