Nonlinear Fiber Optics: Hollow Core Fibers

This lecture covers the concept of nonlinear compensation using the nonlinear Fourier transform, treating fiber nonlinearities as essential elements in fiber communication systems. It discusses hollow core fibers, which guide light within a hollow region with low nonlinearity and potential low transmission loss. The lecture explores the guiding mechanisms, applications in high-capacity data transmission, power delivery, and UV light guidance. It also delves into achieving higher laser peak powers through ultrafast amplification, issues with ultrafast amplification, and amplification of laser pulses using pulsed laser amplifiers. The challenges with pulse intensities inside an amplifier and the technique of chirped pulse amplification are also addressed.
