3. Major areas of research:
My research is at the boundary between material and energy science in the context of simulation, design, measurement and precision fabrication. I research optical simulation and measurement techniques to characterize the geometry or optical performance of nanophotonics components. This is of interest to industries such as nanophotonic device design and manufacturing. The need for optical techniques for fabrication and measurement based on simulation results in a design guidance is growing as technology moves forward, pushing limits of component tolerance and specification. There are few academic research programs with this focus, and the need for graduates with this expertise is strong and growing. The research falls under one or more of the following categories: (1) new measurement and simulation methods and techniques, (2) extending analysis methods or measurement capabilities, (3) establishing calibration methods, and (4) evaluating simulation and measurement uncertainty. These categories have been applied to the general areas of (i) nona-optics and nano-structure metrology and (ii) nano-scale optics and precision components, i.e., nanophotonics (simulation, experiment, fabrication and measurement), plasmonics application (e.g., plasmonics photocatalytic, plasmonic solar cells, biosensors, metamaterials, near-field optics, and nano/micro-optical system), photonic crystal and fiber optics.
Nanophotonics (experiment fabrication and simulation), Electromagnetic field simulation, Photocatalytic application, Green energy, Biosensors, Metamaterials, Biophotonics, Near-field optics, Plasmonics, Nano/Micro-optical System, Photonic crystal and related applications, LED Lighting, Fiber optics, and Plasmonic Solar Cells
Hybrid plasmonic nanostructures (HPNs) are a combination of structured metal and dielectric materials in the nanoscale. HPNs possess special optical and electrical effects which are applicable to the diverse applications on water purification and other nanophotonic devices, such as nanoantennas and bio-sensors. The water purification technology will compliment existing water treatment technologies where the HPNs based water purification technology is targeted for the treatment of industrial waste water containing organic compounds, metals, and micro-organisms. In this project, the investigated HPNs will be performed by using the simulation and experiment methods simultaneously.
In this project, we will focus on the design and analysis of high throughput of nanoscale plasmonic metamaterial for light manipulation and energy harvesting. We will aim to promote the development of nanoplasmonic metamaterials for applications in light manipulation and energy harvest, such as plasmonic solar cell, plasmonic nanoantenna and highly sensitive plasmonic biosensors. For achieving this purpose, four research steps will be carried out base on our previous works: design, fabrication, measurement, and application. In addition, a numerical method by using the finite element method will be performed to simulate and design the tunable efficiency and nonlinear enhancement of electromagnetic resonances of various plasmonic metamaterials.
A photonic crystal fiber based on surface plasmon resonance (PCF-SPR) sensing of a gold layer or gold nanoparticles will be investigated. The sensor has two advantages: polarization independence and less noble metal consumption. The coupling characteristics and sensing performance of the sensor are performed by using by the finite-element method (FEM) based on Maxwell's equations. The characteristics of birefringer, foundmantal modes and optical loss spectrum of the PCF-SPR sensor will be discussed in detail in this project.
