Abstract
This paper presents experimental results in the field of photonic crystals investigation. There are presented our results of experimental investigation of one-dimensional photonic crystals appearing in nature, two-dimensional photonic crystals we formed in LiNbO3 and thin photoresist layers and results of our investigation of chromatic dispersion of photonic crystal fibers as well as the influence of fiber bending on their transmittance.
Highlights
Submicron structures known as photonic crystals (PCs) attract great attention because of their unique optical properties
We demonstrate experimental investigations on the 1D PCs in nature, planar 2D PCs and 2D PC formed in photonic crystal fibers
In our experiments we investigated photonic crystal fiber made by Centaurus Technologies, Australia (Fig. 9)
Summary
Submicron structures known as photonic crystals (PCs) attract great attention because of their unique optical properties. First attempts of their implementation in technology show improvement of optical and electrical properties of optoelectronic devices. Photonic crystals are formed by periodic inhomogeneities of the refractive index with periodicity near the wavelength of an interaction light. Such PC’s show typical effect of wavelength selection known as photonic band gap. We demonstrate experimental investigations on the 1D PCs in nature, planar 2D PCs and 2D PC formed in photonic crystal fibers. Photonic crystal of one (1D), two (2D) and three dimensional (3D) arrays are found in natural world and became the topic of the scientific studies [2, 3] (Fig. 1)
