Research Interests Curriculum Vitae Selected Publications About My Students Professional Activities
Research Interests
My research involves balanced theoretical and experimental exploration outlined as follows:
(1)
Orthogonal Frequency Division Multiplexing (OFDM) techniques for both optical
and wireless applications (Click here to access our optical
OFDM papers)
(2) Coherent optical communications, and optical signal processing and
equalization
(3) All-Optical packet switching, wavelength conversion and novel
optical network architecture
(4) Polarization effects in optical fiber including PMD and PDL in
linear and nonlinear systems
(5)
RF photonics involving RF signal generation, characterization, transmission and
processing
Currently I am looking for postgraduate
students who would like to develop technical skills in above mentioned research
directions.
