Background:

Fiber-optic communication systems suffer from chromatic dispersion, leading to signal degradation.
Wide spectral sources exacerbate dispersion issues, necessitating effective compensation methods.
Existing dispersion compensation techniques may lack tunability or adaptability.

Purpose of the Study:

To analyze and design a novel dispersion-compensating fiber-optic filter.
To enable dynamic tuning for compensating laser frequency drift due to environmental factors.
To provide a fabrication methodology for chirped and tapered refractive-index variations.

Main Methods:

Detailed analysis of dispersion-compensating fiber-optic filter design parameters.
Fabrication via ultraviolet radiation exposure of photorefractive fibers.
