W1HeteroCavity

class picazzo3.phc.hetero.cell.W1HeteroCavity(*args, **kwargs)

Photonic Crystal Waveguide HeteroCavity consisting of a W1 waveguide with adjusted pitch in the cavity. The unit cells for the waveguide and the cavity can be chosen seperately, as well as the different lattice pitches.

Parameters:

cavity: PCell, optional

The cavity child cell (autogenerated)

cavity_defect_unit_cell: PCell, optional

The Photonic Crystal unit cell of the cavity lattice. By default it is empty.

cavity_unit_cell: PCell, optional

The Photonic Crystal unit cell of the cavity lattice

mirror: PCell, optional

The mirror child cell (autogenerated)

mirror_defect_unit_cell: PCell, optional

The Photonic Crystal unit cell of the mirror waveguide. By default it is empty.

mirror_unit_cell: PCell, optional

The Photonic Crystal unit cell of the mirror lattice

n_o_cladding_layers: int and number > 0, optional

cell_instances: _PCellInstanceDict, optional

name: optional

The unique name of the pcell
