  Research Interests

Since the first demonstrations of the carbon-nanotube (CNT) mode-locked lasers in 2003, over the years, it has bloomed into a new field of Nano-Carbon Photonics, using CNT and other nano-carbon materials for various laser and photonics applications.

We are interested in developing new industrial applications using these advanced laser pulsed sources, for examples

1. High-speed, high-sensitivity optical sampling oscilloscope using special long-wavelength femtosecond CNT lasers, for the optical communication industry

2. Non-contact, high-precision 3-D profile measurement system, using a high-repetition rate short-cavity CNT laser for the automobile industry

3. Short pulse seed lasers for the material processing and laser micro-machining industry

Our recent research interests include:

  • Novel highly-reliable laser mode-locking technique.
  • Integrated optical functional devices using new optical materials.
  • Rare-earth-doped fiber amplifiers and their applications.
  • Applications of short pulse lasers in multidisciplinary research.
