Thesis Research

• Dispersion induced ISI optimization in multimode fiber using spatial light modulator (SLM), polarization controllers, and adaptive optics.
  


• Performed experiments on a 10 Gb/s multimode transmission system, wrote codes in LabVIEW to interact with SLM and motorized polarization controllers, optimized ISI by adaptively enhancing the polarization and phase.



• Maximized the eye opening by changing the input launched field, defined different imaging structures to enhance phase, amplitude, and polarization, found the optimal solution for each structure by casting the problem into a convex format, developed adaptive algorithms to perform the optimization in the lab.


• Graded-index multimode fiber modeling to investigate the effect of index imperfections such as curvature, twisting, and birefringence on the modal and polarization coupling.
  


• Found a solution for the perturbed field coupling equations, analyzed the effect of random bends and twists on the differential group delays, impulse response, bandwidth, intensity patterns and state of polarization.
