Light propagation in free space with fourier transform
Project description
Light propagation
Lightprop2d includes class 'Beam2D' to transform intitial field distribution
using fourier transform from x-y field profile to kx-ky spectrum.
You can use both numpy and cupy backends with use_gpu
key of Beam2D class.
You can install it as follows
pip install lightprop2d==1.0rc3
Check out the Code Reference for details on the 'Beam2D' methods.
Example 1: Random beam propagation
import matplotlib.pyplot as plt
from lightprop2d import Beam2D, random_round_hole, um, nm
# All input data are in cm
# XY grid dimensions
npoints = 256
# XY grid widening
beam_radius = 25*um # 25 um
area_size = 200*um # 200 um
# Wavelength in cm
wl0 = 632*nm
beam = Beam2D(area_size, npoints, wl0, init_field_gen=random_round_hole,
init_gen_args=(beam_radius,))
plt.imshow(beam.iprofile)
plt.show()
beam.propagate(100*um)
plt.imshow(beam.iprofile)
plt.show()
