Computational Analysis of Dispersion in Photonic Crystal Fibers

This program is developed in MATLAB to computationally analyze dispersion phenomena in photonic crystal fibers (PCFs). Photonic crystal fibers represent a novel class of optical fibers where light propagation is controlled through photonic crystal core structures, enabling precise manipulation of optical properties. With extensive applications in optical communications, photonics, and optical sensing technologies, PCFs demonstrate significant potential for advanced photonic devices. Our implementation employs numerical methods to accurately compute fiber dispersion characteristics and simulate light propagation behavior, facilitating deeper understanding and analysis of optical properties. The core algorithm likely utilizes finite-difference or plane-wave expansion methods to solve Maxwell's equations in periodic dielectric structures. Key functions may include mode solver implementations, dispersion curve calculations, and effective index computations. The program features realistic simulation capabilities that authentically model light propagation and interaction phenomena within complex fiber geometries. Parameter customization options probably allow users to adjust hole pitch, diameter ratios, and material properties to match specific PCF designs. We anticipate this computational tool will assist researchers in related fields, and welcome valuable feedback and suggestions to further enhance the program's capabilities and better address user requirements. Potential improvements could incorporate advanced visualization modules, optimization algorithms for fiber design, and compatibility with experimental data import functionalities.
