3D Photonic Crystals Build Up By Self-Organization Of Nanospheres
In: DTIC (2006)
Abstract: Band gap structure is the most important information while studying electromagnetic propagation in photonic crystals. A collection of free software is used to set up an analysis tool system for simulation purpose. Because it is desired for application and has been a technique challenge to fabricate a photonic crystal possessing a complete photonic band gap operates at the optical wavelength regime, we study how to optimize the size and position of band gap from the standpoint of long range order, short range order, and material property. We show in this paper that , decreasing the variance of k points on the first Brillouin zone by choosing an appropriate lattice type and adjusting the lattice parameters is required to the formation of a larger complete photonic band gap, and for easy calculations we defined the variance quantity when the coordinates of high symmetry points are known; a local symmetry distorted along some specific directions always opens and extends the gaps, and the effects of structure inversion are considered from this viewpoint; dielectric contrast should have a optimum value to fulfill the requirements of position and size of gap simultaneously rather than an as-high-as-possible value, to prevent the wavelength shift of gap to a shorter range.
