lasy > utils > mode_decomposition.pyto do modal decomposition of arbitrary beams. This works for both a Hermite- and Laguerre-Gaussian basis, and there is a Jupyter notebook tutorial called 'modal_composition.ipynb' which shows how this works. Beams are constructed by specifying the modal coefficients. These beams are then deconstructed to retrieve the original modal coefficients.The modal coefficients are passed and stored as a dictionary of complex values as follows:
# Modal coefficients used to construct the beam modes = {} modes[(0,0)] = 1 -0.2j modes[(0,1)] = -.4 -.2j modes[(1,0)] = 0.5 + 1j modes[(2,2)] = -.05 + .1jFuture updates:
