Plasmonic Enhanced Chiral Metamaterials

Alali F., Kim Y.H., Furlani E.P., University at Buffalo, US

Metamaterials are artificial materials that are engineered to produce various interesting phenomena such as negative refractivity and sub-diffraction-limit imaging. The majority of metamaterials for THz applications have been fabricated using “top-down” techniques. These methods tend [...]

Photoconductivity of GaN Nanowires

Teker K., Siemann A., Istanbul Sehir University, TR

Gallium nitride nanostructures continue to attract great interest due to their applications in optoelectronic devices (UV photodetectors, and light-emitting devices), high-power/high temperature electronics, nanosensing, and piezoelectric nanogenerators. This paper presents a systematic photoconductivity investigation of [...]

Plasmonic nanophotonics and its applications

Chen K.R., Hong J.S., Goncharenko A.V., National Cheng Kung University, TW

Study of surface plasmnon polariton (SPP) effect is a fundamental scientific cross-disciplinary research area with academic importance and critical application potential. We discuss methods for the manipulation of light and plasmonic properties with nanostructures. With [...]

Mid-infrared Silicon Microphotonic Cavities with High Resonance of Q~10^5

Lin P-T, Singh V., Cai Y., Patel N.S., Kimerling L., Agarwal A.M., Massachusetts Institute of Technology, US

One dimensional photonic crystal 1D-PhC silicon waveguide resonators with quality factor, Q~10^5, are demonstrated at mid-infrared wavelengths between 2 um to 5 um. Silicon has several advantages for mid-infrared applications including its broad mid-infrared transmission [...]
