RESEARCH INTERESTS Random fiber gratings for sensor and fiber laser applications Design and fabrication
of random fiber gratings for distributed sensor, random fiber laser and fiber
laser sensor applications. Research and development of fiber Bragg gratings (FBGs) Design and fabrication
of FBGs with complicated structure (chirped, apodized,
superimposed, phase shifted etc.) for applications in fiber lasers, fiber
sensors and optical communication systems. Birefringence in FBGs Examination of laser
induced birefringence; spectral polarization mode dispersion (PMD) and
polarization dependent loss (PDL) in gratings; PMD and PDL compensations
using fiber gratings; fabrication of gratings with ultra
low birefringence. Properties and system impacts of polarization effects in fiber
optic communication systems The interaction
between PMD and PDL/G; the interaction between higher order PMD and frequency
chirp; PMD and PDL induced power penalty in high data rate optical systems. |
