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)    Few-mode fiber based devices and transmission systems

3)    Long-range multi-parameter optical sensing; Coherent optical time domain reflectometry (COTDR)

4)    Coherent optical communications, and optical signal processing and equalization

5)    All-Optical packet switching, wavelength conversion and novel optical network architecture

6)    Polarization effects in optical fiber including PMD and PDL in linear and nonlinear systems

7)    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.
