legume.PhotCryst
- class legume.PhotCryst(lattice, eps_l=1, eps_u=1)
Class for a photonic crystal which can contain a number of layers.
- __init__(lattice, eps_l=1, eps_u=1)
Initialize a photonic crystal.
- Parameters:
lattice (Lattice) – A lattice defining the 2D periodicity.
eps_l (float, optional) – Permittivity of the lower cladding.
eps_u (float, optional) – Permittivity of the upper cladding.
Methods
__init__(lattice[, eps_l, eps_u])Initialize a photonic crystal.
add_layer(d[, eps_b, layer_type])Add a layer to the photonic crystal, on top of all currently existing layers.
add_qw(z, V_shapes, a, M, E0, loss, osc_str)Add an active layer to in the photonic crystal.
add_shape(shapes[, layer, cladding])Add a list of shapes to a given layer.
get_eps(points)Compute the permittivity of the PhC at a set of points.
get_eps_bounds()Returns the minimum and maximum permittivity of the structure.
z_grid([Nz, dist])Define a z-grid for visualization purposes once some layers have been added.
