tidy3d.GdsSlab

class tidy3d.GdsSlab(material, gds_cell, gds_layer=None, gds_dtype=None, gds_scale=1.0, z_cent=0, z_size=1, z_min=None, z_max=None, name=None)

A structure defined through a GDS cell imported through gdspy. All polygons and paths included in the cell are assumed to lie in the xy-plane, with the same center and size in z, and made of the same material. Optionally, the integer gds_layer and gds_dtype index can be provided. If not, all structures in the cell are imported.

__init__(material, gds_cell, gds_layer=None, gds_dtype=None, gds_scale=1.0, z_cent=0, z_size=1, z_min=None, z_max=None, name=None)

Construct.

Parameters

  • material (Material) – Material of the structure.

  • gds_cell (gdspy.Cell) – A GDS Cell containing all polygons and paths to be imported.

  • gds_layer (int, optional) – Layer index to select by. If None, all indexes are taken.

  • gds_dtype (None, optional) – Data type index to select by. If None, all indexes are taken.

  • gds_scale (float, optional) – (micron) Length scale in units of micron.

  • z_cent (float) – (micron) Center of the structure in z.

  • z_size (float) – (micron) Thickness of the structure in z.

  • z_min (None, optional) – (micron) Beginning of the structure along z.

  • z_max (None, optional) – (micron) End of the structure along z.

  • name (str, optional) – Custom name of the structure.

Note

If z_min and z_max are provided, they override z_cent and z_size.
