Studying Focusing Properties of Graded Index Photonic Crystals Made of Material with Different Refractive Index
In this paper we investigate focusing properties of graded index (GRIN) photonic crystal (PC) structures which are composed of different materials with different refractive indices. GRIN PC structure is constructed from air holes in dielectric background. The holes radii are varied in the normal direction to the propagation in such a way that a parabolic effective refractive index is produced. ...
متن کاملPhotonic crystals and negative refractive index materials
We review the research of our group on propagation of electromagnetic waves in photonic crystals (PCs) and micrometer scale left-handed materials (LHMs). The main topics that we focus on regarding PCs are the modification of the spontaneous emission rate of sources embedded into them, their ability to produce beams with high directionality and their negative refraction and focusing properties, ...
متن کاملDiamond-Structured Photonic Crystals with Graded Air Spheres Radii
A diamond-structured photonic crystal (PC) with graded air spheres radii was fabricated successfully by stereolithography (SL) and gel-casting process. The graded radii in photonic crystal were formed by uniting different radii in photonic crystals with a uniform radius together along the Г‑Х direction. The stop band was observed between 26.1 GHz and 34.3 GHz by reflection and transmission meas...
متن کاملSelf-collimation and beam splitting in low-index photonic crystals
We study self-collimation and beam splitting in low-refractive-index photonic crystals created within chalcogenide glass. We propose a beam splitter structure that allows direct experimental verification of photonic-crystal effects at optical wavelengths in a straightforward and definitive manner. The beam splitter provides angular separation of 90 using a highly compact spatial footprint, thus...
متن کاملBandgap properties of two-dimensional low-index photonic crystals
We study the bandgap properties of twodimensional photonic crystals created by a lattice of rods or holes conformed in a symmetric or asymmetric triangular structure. Using the plane-wave analysis, we calculate a minimum value of the refractive index contrast for opening both partial and full two-dimensional spectral gaps for both TM and TE polarized waves. We also analyze the effect of ellipti...
