Metamaterial-Dielectric Photonics Crystal Waveguide Structure

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...

Discrete photonics in waveguide arrays.

In homogeneous arrays of coupled waveguides, Floquet-Bloch waves are known to travel freely across the waveguides. We introduce a systematic discussion of the built-in patterning of the coupling constant between neighboring waveguides. Key patterns provide functions such as redirecting, guiding, and focusing these waves, up to nonlinear all-optical routing. This opens the way to light control i...

Multipactor Analysis in Dielectric Resonator Waveguide Filters

Multipactor breakdown analysis is presented in cylindrical dielectric resonator waveguide filter under its dual-mode behavior. The method of effective electron algorithm with combination of Monte-Carlo method is used to perform the simulation and predict multipactor breakdown thresholds. The breakdown thresholds of the proposed structure are presented for different values of frequency-gap produ...

Photonic crystal waveguide modulators for silicon photonics: Device physics and some recent progress

We review the basic principles, structural designs, and electrical characteristics of photonic crystal waveguide modulators based on slow light Mach-Zehnder interferometers. A number of structural and electrical configurations of photonic crystal waveguide modulators are discussed. In addition to the advantages associated with the slow group velocity, photonic crystal waveguide modulators are f...
