报告简介:

Ultrafast nano-photonics

This talk includes two parts: the first part discusses my recent research on ultrafast nano-photonics and current research activities in my group at the Memorial University of Newfoundland, Canada, and the second part introduces our study on organic bulk heterojunction solar cells with improved efficiency.

Ultrafast nano-photonics is an optical nanotechnology aiming to achieve a spatial resolution beyond the diffraction limit and a temporal resolution at ultrafast scale. I will present my recent research in this field, which includes super-resolution for nanoscale optical data storage and high-speed nanolithography, femtosecond laser microfabrication, femtosecond laser trimming of photonic lightwave circuits, and ultrafast nonlinear photonics of fullerene derivatives breaching quantum limits.

Organic solar cells have attracted considerable attention in recent years for their unique advantages, such as solution processing, flexibility, and low cost. In this talk, I will discuss our effort in developing universal techniques for the improvement of the efficiency of organic solar cells through processing of individual layer in the device and the realization of flexible polymer solar cells on two types of nanostructured bulk heterojunction devices, i.e. poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), and (poly[2-methoxy,5-(2-ethylhexoxy)-1,4-phenylene vinylene]) (MEH-PPV) and PCBM.

Intelligent multiparameter fiber-optic sensors
Fiber-optic sensors have received significant attention for their unique advantages such as immunity to electromagnetic interference, compact size, potential low cost, and the possibility of distributed measurement over a long distance. In this talk, I will present our recent progress in developing techniques to achieve intelligent sensing of multiple environmental parameters
with single-fiber approach, which realize sensing of temperature, strain, humidity, salinity, saccharinity, bend, flow, and refractive index for possible applications as physical and chemical sensors.
