This course will provide a basic understanding of non-linear optics phenomena in optical fibers and optical fiber devices based on these non-linear phenomena. This course will prepare students for the growing non-linear fiber optics based devices especially for coherent narrow and broadband light sources.
Contents: Module 1: Introduction to Nonlinear Fiber Optics-I
Fiber Nonlinearities, Pulse Propagation in fibers, Group Velocity Dispersion, Third-Order Dispersion, Dispersion-induced pulse broadening, Self-phase Modulation, Optical Wave Breaking, Cross-phase Modulation, Modulation Instability, and Fiber Solitons (Bright solitons, high-order solitons, dark solitons). Module 2: Introduction to Nonlinear Fiber Optics-II
Stimulated Raman Scattering (Basic Concepts, Raman Solitons, Vector Theory), Stimulated Brillouin Scattering (Physical process, Brillouin-Gain Spectrum, threshold, techniques for controlling threshold), and Four Wave Mixing (Theory, Phase-Matching techniques). Module 3: Nonlinear Fiber Devices-I
Harmonic Generation, Parametric amplifiers (Basics, Gain spectrum, different pump configurations), Parametric Oscillators, Ultrafast Signal Processing, Quantum Noise and Correlation, and Single-Photon Sources (Basics, Design, Phase matching, and characteristics) . Module 4: Nonlinear Fiber Devices-II
