Second-order parametric interactions in 1-D photonic-crystal microcavity structures

Second-order parametric interactions in 1-D photonic-crystal microcavity structures.

We develop a generalized model for studying second-order parametric interactions in 1-D multilayered photonic structures, accounting for collinear oblique waves and partial pump depletion. This model is used to assess the performance of parametric devices in photonic-crystal microcavity (PCM) structures. Our model shows dramatic enhancement of nonlinear interactions at frequencies for which the...

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...

Hybrid Photonic Crystal Microcavity Switches on SOI

We report the development and characterization of 2-D photonic crystal (PC) microcavity devices on silicon on insulator. The transmission of light through a 2-D PC microcavity near resonance can be switched on and off by modulating the refractive index of the PC. Because silicon has poor electro-optical properties, it is advantageous to insert electro-optic materials inside the air holes. In th...

Modelling photonic crystal devices using second order finite volume method

A second order finite volume scheme is considered [1]. The scheme includes total field scattered field formulation and a perfectly matched layer [2]. It was applied to evaluation of optical properties of photonic crystal waveguides [3]. Reflection and transmission coefficients were studied for a range of frequencies inside the photonic crystal bandgap for different configurations. Our results c...
