Fabrication of 2-D photonic crystals using azo polymers
In this paper, we have reported the fabrication of two-dimensional photonic crystals, using a direct writing method in azo polymers. Periodic structures have been fabricated using the interference patterns of two coherent laser beams. The frequency response of the initial one-dimensional structure shows an attenuation of 19.3dB at 1554nm. The twodimensional structure shows 8.3dB and 11.3dB of a...
متن کاملFabrication of Tetragonal Square Spiral Photonic Crystals
We present a simple, versatile technique for the fabrication of large, three-dimensional gap photonic crystals using glancing angle deposition (GLAD). A tetragonal lattice suitable for a large photonic band gap (PBG) can be synthesized by a regular array of square spiral structures grown from a simple, prepatterned substrate using physical vapor deposition and advanced substrate motion. Tetrago...
متن کاملFabrication of photonic band-gap crystals
We describe the fabrication of three-dimensional photonic crystals using a reproducible and reliable procedure consisting of electron beam lithography followed by a sequence of dry etching steps. Careful fabrication has enabled us to define photonic crystals with 280 nm holes defined with 350 nm center to center spacings in GaAsP and GaAs epilayers. We construct these photonic crystals by trans...
متن کاملSemiclassical Coupled Wave Theory for TM-waves in 1-D Photonic Crystals
A one dimensional periodic structure with high refractive index contrast can serve as a photonic crystal [1–5]. Among the common theoretical methods for wave motion in such structures, the coupled wave approach offers superior physical insight and gives simple analytical results in limiting cases. Unfortunately, the conventional coupled wave theory of Kogelnik [6–8] fails in the case of high re...
متن کاملCoupled waveguide modes in hexagonal photonic crystals.
We investigate the modes of coupled waveguides in a hexagonal photonic crystal. We find that for a substantial parameter range the coupled waveguide modes have dispersion relations exhibiting multiple intersections, which we explain both intuitively and using a rigorous tight-binding argument.
