Sensors Based on Plasmonic-Photonic Coupling in Metallic Photonic Crystals

An optical sensor based on the coupling between the plasmonic and photonic resonance modes in metallic photonic crystals is investigated. Large-area metallic photonic crystals consisting of periodically arranged gold nanostructures with dimensions down to sub-100 nm are fabricated using solution-processible gold nanoparticles in combination with interference lithography or interference ablation...

Photospin-orbit coupling in photonic structures.

We show that the inclusion of nonlocality in the constitutive relations in photonic structures has important repercussions in their eigenmode configuration and distribution. In the case of optical activity, the primary manifestation of nonlocality, these features are traced to a photospin-orbit interaction analogous to the electron spin-orbit interaction in asymmetric semiconducting compounds; ...

Fabrication of Integrated Graphene Photonic Devices

Graphene is a single-atom-thick layer of carbon atoms in a honeycomb lattice. It is currently a popular material for study in condensed matter physics and related fields [1-6]. The material has a large number of proposed potential applications including integrated photonic devices. Saturable absorption and photocurrent generation has already been successfully demonstrated [1,2]. We aim to study...

Theoretical investigation of graphene-based photonic modulators

Integration of electronics and photonics for future applications requires an efficient conversion of electrical to optical signals. The excellent electronic and photonic properties of graphene make it a suitable material for integrated systems with extremely wide operational bandwidth. In this paper, we analyze the novel geometry of modulator based on the rib photonic waveguide configuration wi...
