Download or read book The Development of Layered Photonic Band Gap Structures Using a Micro-transfer Molding Technique written by Kevin Jerome Sutherland and published by . This book was released on 2001 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last ten years, photonic band gap (PBG) theory and technology have become an important area of research because of the numerous possible applications ranging from high-efficiency laser diodes to optical circuitry. This research concentrates on reducing the length scale in the fabrication of layered photonic band gap structures and developing procedures to improve processing consistency. Various procedures and materials have been used in the fabrication of layered PBG structures. This research focused on an economical micro transfer molding approach to create the final PBG structure. A poly dimethlysiloxane (PDMS) rubber mold was created from a silicon substrate. It was filled with epoxy and built layer-by-layer to create a 3-D epoxy structure. This structure was infiltrated with nanoparticle titania or a titania sol-gel, then fired to remove the polymer mold, leaving a monolithic ceramic inverse of the epoxy structure. The final result was a lattice of titania rods that resembles a face-centered tetragonal structure. The original intent of this research was to miniaturize this process to a bar size small enough to create a photonic band gap for wavelengths of visible electro-magnetic radiation. The factor limiting progress was the absence of a silicon master mold of small enough dimensions. The Iowa State Microelectronics Research Center fabricated samples with periodicities of 2.5 and 1.0 microns with the existing technology, but a sample was need on the order of 0.3 microns or less. A 0.4 micron sample was received from Sandia National Laboratory, which was made through an electron beam lithography process, but it contained several defects. The results of the work are primarily for from the 2.5 and 1.0 micron samples. Most of the work focused on changing processing variables in order to optimize the infiltration procedure for the best results. Several critical parameters were identified, ranging from the ambient conditions to the specifics of the procedure. It is believed that most critical for fabrication of high quality samples is control of the temperature of the sample during and after infiltration, and the rate and amount of time spent applying epoxy to the PDMS.

Book Synopsis Development of a Photonic Band Gap Structure Through Titania Sol-gel Coating of Polystyrene Spheres by : Sara Lea Rolfe
Download or read book Development of a Photonic Band Gap Structure Through Titania Sol-gel Coating of Polystyrene Spheres written by Sara Lea Rolfe and published by . This book was released on 1998 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonic band gap structures are ordered, periodic dielectric structures, which have interesting optical properties and many applications including preventing spontaneous emission and filtering. Using the sol-gel process, colloidal polystyrene particles were fully coated with silica and titania and then the coated spheres were crystallized into an ordered arrangement of spheres by heating. The sol-gel titania was fully dense and shrank 30.4% from the green state to the sintered state. The colloidal polystyrene particles decomposed during heating at 335°C while the sol-gel titania goes through a three step transformation starting at 400°C and ending at 550°C. After heating to 550°C, X-ray diffraction shows that the titania is anatase in structure. Inverse structures, with dimensions in the optical range, were developed with varying degrees of order. Slow drying in a high humidity atmosphere, decreased sample mold thickness, and a sol-gel precursor with large R groups aided in improving the short-range periodicity. dip-coating. Areas of ordered holes separated by thick titania sections were created using dip-coating. The best order was obtained by centrifuging the coated spheres. As an alternative route, the uncoated polystyrene spheres crystallized into well-ordered grains which could be infiltrated by the sol-gel solution. Spectroscopy results did not indicate a definite band gap where expected due to imperfection of the periodicity and surface roughness.
Book Synopsis Method of Manufacturing Flexible Metallic Photonic Band Gap Structures, and Structures Resulting Therefrom by :
Download or read book Method of Manufacturing Flexible Metallic Photonic Band Gap Structures, and Structures Resulting Therefrom written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A method of manufacturing a flexible metallic photonic band gap structure operable in the infrared region, comprises the steps of spinning on a first layer of dielectric on a GaAs substrate, imidizing this first layer of dielectric, forming a first metal pattern on this first layer of dielectric, spinning on and imidizing a second layer of dielectric, and then removing the GaAs substrate. This method results in a flexible metallic photonic band gap structure operable with various filter characteristics in the infrared region. This method may be used to construct multi-layer flexible metallic photonic band gap structures. Metal grid defects and dielectric separation layer thicknesses are adjusted to control filter parameters.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of the work, is to study nonlinear parametric interactions, such as nonlinear frequency conversion and all-optical switching, in miniaturized photonic band gap materials. In particular, we wish to address highly efficient chi(sup 2) and chi(sup 3) processes in the short- wavelength range (less than 0.4 micrometers) to far (8-12 micrometers) IR regions of the electromagnetic spectrum near the photonic band edge of one-dimensional photonic crystals. The work is performed in collaboration with the group of Dr. C. Bowden, Weapons Science Directorate, Missile Research Development & Engineering Center, U.S. Army Aviation and Missile Command, Redstone Arsenal, AL 35898-5000. According to the previous reports related to the first 9 months of the contract, the work has been performed and continued following different activities, as described in technical report.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the NATO Advanced Research Workshop on Localization and Propagation o[ Classical Waves in Random and Periodic Media held in Aghia Pelaghia, Heraklion, Crete, May 26- 30, 1992. The workshop's goal was to bring together theorists and experimentalists from two related areas, localization and photonic band gaps, to highlight their common interests. The objectives of the workshop were (i) to assess the state of-the-art in experimental and theoretical studies of structures exhibiting classical wave band gaps and/or localization, (ii) to discuss how such structures can be fabricated to improve technologies in different areas of physics and engineering, and (iii) to identify problems and set goals for further research. Studies of the propagation of electromagnetic (EM) waves in periodic and/or disordered dielectric structures (photonic band gap structures) have been and continue to be a dynamic area of research. Anderson localization of EM waves in disordered dielectric structures is of fundamental interest where the strong ei-ei interaction efFects entering the eIectron-localization are absent.
