Highly tunable ultra-narrow-resonances with optical nano-antenna phased arrays in the infrared
Shi-Qiang Li, Wei Zhou, Peijun Guo +6
We report our recent development in pursuing high Quality-Factor (high-Q factor) plasmonic resonances, with vertically aligned two dimensional (2-D) periodic nanorod arrays. The 2-…
Broadband resonances in ITO nanorod arrays
Shi-Qiang Li, Kazuaki Sakoda, John B. Ketterson +1
In the nanophotonics community, there is an active discussion regarding the origin of the selective absorption/scattering of light by the resonances with nanorod arrays. Here we re…
TCO Nanostructures as building blocks for nanophotonic devices in the infrared
Shi Qiang Li, Leonidas E. Ocola, Robert P. H. Chang
Transparent conducting oxides (TCOs), in general, are degenerated semiconductors with large electronic band-gap. They have been widely used for display screens, optoelectronic, pho…
Five-Fold Reduction of Lasing Threshold near the First -Pseudogap of ZnO Inverse Opals
Michael Scharrer, Heeso Noh, Xiaohua Wu +4
We report room temperature lasing in ZnO inverse opal photonic crystals in the near-ultraviolet (UV) frequency. We observe random lasing due to disorder in the structures when the…
Photoluminescence modification by high-order photonic band with abnormal dispersion in ZnO inverse opal
Heeso Noh, Michael Scharrer, Mark A. Anderson +2
We measured the angle- and polarization-resolved reflection and photoluminescence spectra of ZnO inverse opals. Significant enhancement of spontaneous emission is observed. The enh…
Self-optimization of optical confinement in ultraviolet photonic crystal slab laser
Alexey Yamilov, X. Wu, X. Liu +2
We studied numerically and experimentally the effects of structural disorder on the performance of ultraviolet photonic crystal slab lasers. Optical gain selectively amplifies the…
