Python code to calculate light propagation through optical fibers following the approach presented in Ghatak and Thyagarajan, An Introduction to Fiber Optics <https://doi.org/10.1017/CBO9781139174770>. Far-field fiber calculations are based on Chen, Foundations for Guided-Wave Optics <https://doi.org/10.1002/0470042222>.
