Research Interests

Computer Modeling:	Modeling and simulation of nanophotonic and optoelectronic devices.

Devices fabrication :	Design and realization of optoelectronic devices such as semiconductor lasers, modulators and waveguides using novel nano-materials.

Research Highlight

Previous studies in computer simulation of semiconductor lasers (1994 ¡V 2003):

¡P Developed computer simulators for optoelectronic devices including long-wavelength distributed feedback and vertical-cavity surface-emitting lasers, modulators etc for telecommunication applications.

¡P His work (i.e., IEEE JQE, 30, pp.1389-1395, 1994) had been adopted to develop laser simulator namely ¡¥LASER PLUS¡¦ in Lucent Technologies Inc. USA to study the transient response of distributed feedback lasers.

¡P He also contributed to the understanding on the modulation response of vertical-cavity surface-emitting lasers (VCSELs). His understanding and knowledge in VCSELs had been summarized in form of a text book.

Previous studies in ultraviolet light-emitting devices and lasers using metal-oxide based nanomaterials (2001 ¡V 2010):

¡P Demonstrate the realization of high-efficiency light-emitting devices using nanostructured ZnO, ZnMgO, SnO₂, InSnO₂, AlN etc as the active media.

¡P Fabrication of room-temperature ultraviolet lasers by using ZnO based materials. The problems of inefficiency confinement of light and carriers had been solved for the realization of world-first ZnO based random laser diodes.

¡P His work in ZnO lasers has been highlighted in the 'Newsbreaks' of the February 2004 issue (Vol. 40, No. 2) of Laser Focus World.

¡P Again, his ZnO lasers work was reviewed by Laser Focus World on December 2008 issue in the article ¡¥PHOTONIC FRONTIERS: SEMICONDUCTOR UV LASERS: Materials are a tough challenge for ultraviolet diode lasers¡¦.

¡P Nanyang Technological University recognized his contribution on the realization of ZnO based laser diodes and awarded him and his collaborator a Nanyang Award for Research & Innovation in 2006.

Research activities in photonic devices (2010 ¡V now):

¡P His current research activities involved the design, analysis and realization of lasers, plasmonic waveguides, solar cells, etc using metal-oxide and carbon based nanowires and nano-dots materials.

¡P He has developed computer simulators to study the optical properties of plasmonic waveguides and lasers.

¡P He has contributed to the design and fabrication of narrow-beam high-power THz quantum cascade lasers (QCLs). As none of the currently available THz QCLs can achieve such a high quality beam control, our work published in 2013 APL was highlighted in the ¡§research highlights¡¨ of the April 2013 issue of Nature Photonics.

¡P He has demonstrated for the first time the lasing emission from carbon-nanodots dispersed in solvents.

¡P He has realized ~300 nm emission from SnO₂ nanodots which can be used to fabricate deep UV-photonics.

¡P First demonstration of deep UV (~310 nm) upconversion nanoparticles laser under 980 nm excitation.

Recent development of large equipment and facility for the Department and University (2011 ¡V now):

¡P Femtosecond pump-probe spectroscopy for time-resolved probe of structural dynamics of organic and inorganic materials.

¡P Integration of the near-field scanning optical microscope with the femtosecond pump-probe spectroscopy for the optical studies (Raman/ photoluminescence) of nanostructure materials.

¡P Realization of sub-micron fluorescence imaging with wavelength from deep UV (200 nm) to visible and to infrared (2.5 mm) regimes.

¡P Involved in the establishment of the first university cleanroom including class 100, 1000 and 10,000 regions with total area of ~500 m² for the nanomaterials fabrication and characterization.
