Chen-An Lin Award Candidate Micrometer-sized Chiral Lasers with Metal/GaN Double-Spiral Nanowire Cavity
Chen-An Lin;Min-Hsiung Shih

The compact size, room temperature operated circular polarization laser was demonstrated with the metal/GaN double-spiral cavity. The lasing action was observed at 363 nm ultraviolet wavelength, with the smallest footprint and highest circular polarization found to be 2 μm and +1.6 of the dissymmetry factor respectively.

Wei Tan Award Candidate Study on bowtie plasmonic notch for nanoparticle trapping and sensing
Wei Tan;Yi-Chang Lin;Po-Tsung Lee

We propose a nanotweezers design named plasmonic bowtie notch for nanoparticle trapping and sensing. Simulation shows that an 100 nm polystyrene sphere can be trapped with threshold power density of 1.1 mW/square micrometer and a sensitivity of 0.1 nm reflection dip shift per 1 nm change of trapped particle size.

Hyperbolic Metamaterials
Igor Smolyaninov

Hyperbolic metamaterials were originally introduced to overcome the diffraction limit of optical imaging. Soon thereafter it was realized that hyperbolic metamaterials demonstrate a number of novel phenomena resulting from the broadband singular behavior of their density of photonic states. These novel phenomena and applications include super resolution imaging, new stealth technologies, enhanced quantum-electrodynamic effects, thermal hyperconductivity, superconductivity, and interesting gravitation theory analogues. I will review typical material systems, which exhibit hyperbolic behavior and outline important applications of hyperbolic metamaterials.

Enoch Rufus Young Award Candidate Hybrid Plasmonic Waveguide-based Multimode Interference for XOR Logical Gate
Enoch Rufus Young

We propose an XOR logical gate based on hybrid plasmonic waveguide using multimode interference. The destructive multimode interference is generated in a single plate by utilizing an adjacent phase modulator. The highest contrast ratio can reach 11.5dB in simulation and distinctive brightness at output port is observed in experiment.

Jhu-Hong Li Award Candidate Quasi-0D Plasmonic Nanodot Lasers with Extremely Small Mode Volume
Jhu-Hong Li;Tien-chang Lu

We demonstrate a quasi-zero dimensional (quasi-0D) plasmonic nanodot laser by ZnO nanowire intersecting with Ag grating. The effective mode volume is 100 times smaller than that of two-dimensional SPP nanolaser. The strong dispersion relation cause group velocity 1/165 times of the light speed and the spontaneous emission factor is 0.8.

Chang Hung-Ming Award Candidate Generation of convergent beams by Surface Magnetoplasmon Emission
Chang Hung-Ming;Lan Yung-Chiang

In this study, we design a magnetic lens for surface magnetoplasmons to generate a convergent beam in terahertz region. The proposed structure is a semiconductor-insulator-semiconductor substrate with chirped gratings on the substrate based on the phase matching condition and can be well manipulated by the external magnetic field.
