Aluminum Coated Nanostructure Arrays for High-Throughput Surface Plasmon Detections
Kuang-Li Lee;Pei-Kuen Wei

High-throughput measurement of biomolecular interactions can benefit biological research. A low-cost surface plasmon resonance imaging platform, comprising of aluminum coated nanoslit arrays and an image device, is developed. These sensing arrays showed tunable evanescent depth with refractive index resolution of ~10-5. We demonstrated the applications for protein-protein and drug-cells interactions

Highly Efficient and Stable Perovskite Nanowire Arrays Based Optical Device with High Polarized Emission
KONTHOUJAM JAMES SINGH;Ya-Hui Chang;Yu-Wei Shih;An-Chen Liu;Hao-Chung Kuo

In this work, highly ordered perovskite nanowire (NW) arrays is reported by incorporating inkjet printing and an anodic aluminum oxide (AAO) confinement strategy emitting high polarized light with polarization degree up to 0.84 and high photoluminescence external quantum efficiency of 21.6%.

High Performance Van der Waals Heterostructure Photodetectors Based on Black Phosphorus
Tian Yun Chang

We proposed a vertically stacked van der Waals heterostructure photodetector based on black phosphorus, which exhibits broadband photodetection with high quantum efficiency and high speed photoresponse at room temperature due to strong vertical electric field and high out-of-plane mobility of BP. We also utilized our detector for mid-infrared imaging applications.

Perovskite Quantum Dot Lasing in a Gap-Plasmon Nanocavity with Ultralow Threshold
Yu-Hung Hsieh;Bo-Wei Hsu;Kang-Ning Peng;Kuan-Wei Lee;Chih-Wei Chu;Shu-Wei Chang;Hao-Wu Lin;Ta-Jen Yen;Yu-Jung Lu

Here, we demonstrate a continuous-wave nanolasing from a single lead halide perovskite (CsPbBr3) quantum dot in a plasmonic gap-mode nanocavity with an ultralow threshold of 1.9 Wcm−2 under 120 K. The calculated ultrasmall mode volume (∼0.002 λ3) and the large Purcell enhancement dramatically enhance the light-matter interaction, thus facilitating lasing.

Routing the Second-Harmonic Signals from a WSe2 Monolayer using a Plasmonic Nanocircuit
Pei-Yuan Wu;Tzu-Yu Chen;Wei-Qing Lee;Chang-Hua Liu;Chen-Bin Huang

We experimentally demonstrate the second-harmonic signals generated in a WSe2 monolayer can be effectively coupled into a plasmonic nanocircuit. For the first time, we show the resulting surface plasmon polaritons can be selectively routed.
