Introduction to Photonic Crystal Fibers


Photonic crystal fibers (PCFs) have emerged as a promising platform for a wide range of applications due to their unique properties and design flexibility. These fibers consist of a periodic array of microstructured air holes that run along the length of the fiber, which enables precise control over the propagation of light. Of particular interest are hollow core fibers, which are characterized by a central void that enables light to be confined within the hollow core. As research and development in this field continue to advance, photonic crystal fibers are poised to play a pivotal role in the next generation of optical communication and sensing systems.

The students task is to provide a comprehensive overview of PCFs with a focus on characterizing their distinctive linear and nonlinear properties.
