ofiber is a Python library for analyzing guided-wave propagation in optical fibers and related dielectric waveguiding structures. It provides analytical and numerical tools for mode analysis, dispersion engineering, and far-field radiation modeling.
The theoretical framework closely follows well-established treatments in:
Ghatak & Thyagarajan, An Introduction to Fiber Optics (Cambridge University Press) https://doi.org/10.1017/CBO9781139174770
Chen, Foundations for Guided-Wave Optics (Wiley) https://doi.org/10.1002/0470042222
The accompanying examples and notebooks are intended to support instruction, research reproducibility, and optical design workflows.
Installation
With pip:
pip install ofiber
Or with conda from conda-forge:
conda install -c conda-forge ofiber
