Select a topic for your final presentation by May 1, 2020.   List of Potential Topics 

The final pretensions will tentatively be held on the following two days (via Zoom):  ()

All are required to attend and participate in both sessions.   Students will be selected randomly to make their presentations.   

Please make your presentations clear, educational and entertaining, not exceeding 20 min.

Final Presentations:  

Monday (5/11- 3-5:30pm) - Zoom Link  

Tuesday (5/12, 3-5:30pm) - Zoom Link

  • An oral presentation ( maximum of 18-20 minutes) is expected on each subject.
  • Students should also share (upload) their presentations to a OneDrive shared folder. 
  • Students will be asked randomly during each session to present.  
  • There will be an additional 3-5 minutes for question and answer at the end of each presentation.
  • All students enrolled are required to attend every presentation by their fellow classmates and preferably participate in the discussions.
  • The presentations should be clear and understandable by all the students. Use equations sparingly (only if needed) and avoid crowded viewgraphs. Remember that you are responsible for making the class understand the topic. Do not try to cover to much material.

Course Syllabus

  • Introduction (historical overview, applications of NLO)
  • Nonlinear Susceptibilities (χ(2) and χ(3) processes, nonlinear refraction and absorption)
  • Classical Anharmonic Oscillator Model
  • Properties of Nonlinear Susceptibilities (symmetries, Kramers-Kronig dispersion relations)
  • Wave Propagation in NLO Media (coupled amplitude equations for χ(2) processes, phase matching, second harmonic generation, sum and difference frequency generation, optical parametric processes, cascading nonlinearities)
  • Quantum Mechanical Treatment of Nonlinear Susceptibilities
  • χ(3) Processes (electronic, vibrational and rotational effects, optical Kerr effect, self-focusing, wave-mixing, bistability, phase-conjugation, beam coupling, solitons)
  • Photo-Refractive Nonlinearities
  • Stimulated Light Scattering (stimulated Raman, Brillouin, and Rayleigh scattering)
