چکیده

July 2003 Two-dimensional photonic crystal accelerator structures∗ Benjamin M. Cowan† Stanford Linear Accelerator Center, Stanford University, Stanford, California 94309 Abstract Photonic crystals provide a method of confining a synchronous speed-of-light mode in an all-dielectric structure, likely a necessary feature in any optical accelerator. We explore computationally a class of photonic crystal structures with translational symmetry in a direction transverse to the electron beam. We demonstrate synchronous waveguide modes and discuss relevant parameters of such modes. We then explore how accelerator parameters vary as the geometry of the structure is changed, and consider trade-offs inherent in the design of an accelerator of this type.

Temperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...

Tunable Defect Mode in One-Dimensional Ternary Nanophotonic Crystal with Mirror Symmetry

In this paper, the properties of the defect mode in the photonic band gap ofone-dimensional ternary photonic crystals containing high temperature superconductorlayer (SPCs) have been theoretically investigated. We considered the quasi-periodiclayered structures by choosing two order of ternary Thue-Morse structures with mirrorsymmetry. We investigated the transmission spectra of these structure...

A New Method for Calculating Propagation Modes of a One Dimensional Photonic Crystal (RESEARCH NOTE)

Photonic band-gap (PBG) crystals offer new dimensions of freedom in controlling propagation of electromagnetic waves. The existence of stop-bands in the transmission characteristic of these crystals makes them a suitable element for the realization of many useful microwave and optical subsystems. In this paper, we calculate the propagation constant of a one-dimensional (1-D) photonic crystal by...

Design and Analysis of a Novel Hexagonal Shaped Channel Drop Filter Based on Two-Dimensional Photonic Crystals

In this paper a new optical channel drop filter (CDF) based on two dimensional (2-D) photonic crystals (PhC) with hexagonal shaped structure is proposed and numerically demonstrated by using the finite-difference-time-domain (FDTD) and plane-wave-expansion (PWE) techniques. Photonic crystals (PhCs) are artificial dielectric nanostructure materials in which a periodic modulation of the material ...

Design of Photonic Crystal Resonant Cavity Using Overmoded Dielectric Photonic Band Gap Structures

An overmoded photonic crystal resonant cavity with two dimensional dielectric lattice structures is proposed and simulated. The dominant mode is a higher-order TM03-like at the frequency of 31.14 GHz, the fundamental mode and most other modes are not supported by the cavity. The structure would be potential for application in accelerator, gyrotron and klystron in Ka-band. DOI: 10.2529/PIERS0610...
