PhotCryst
(lattice, eps_l: float = 1, eps_u: float = 1)¶ Class for a photonic crystal which can contain a number of layers.
-
__init__
(lattice, eps_l: float = 1, eps_u: float = 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_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. -
