class
picazzo3.filters.mzi.cell.
MZI
(*args, **kwargs)¶ Generic MZI, taking a splitter, combiner and two _MziArm objects. You have to specify the transformations yourself.
Parameters: arm1: PCell and MZIArm
The South arm of the MZI
arm1_port_names: length == 2
port names for the south arm ports connected to splitter and combiner. Default = (‘in’, ‘out’)
arm2: PCell and MZIArm
The North arm of the MZI
arm2_port_names: length == 2
port names for the north arm ports connected to splitter and combiner. Default = (‘in’, ‘out’)
combiner: PCell
The combiner of the MZI
combiner_port_names: length == 2
port names for the combiner ports to the arms. Default = (‘in1’, ‘in2’)
splitter: PCell
The splitter of the MZI
splitter_port_names: length == 2
port names for the splitter ports to the arms. Default = (‘out1’, ‘out2’)
external_port_names:
Map of the free instance terms/ports to the names of external terms/ports.Format is a dict {‘inst:term’ : ‘new_term_name’}.If a term/port is not listed, the format instname_portname will be used
name:
The unique name of the pcell
Other Parameters: child_cells: locked
links: locked

Layout
¶ Parameters: combiner_transformation: GenericNoDistortTransform
splitter_transformation: GenericNoDistortTransform
view_name: str and ( Alphanumeric string or Contains _$ )
The name of the view
flyline_layer: ( __Layer__ ), *None allowed*
layer to draw flylines of physically unconnected links
flyline_width: float and number > 0
line width of the flylines
netlist_view: NetlistView
Netlist view in the same cell on which this Layout is based. Normally no need to manually override.
Other Parameters: child_transformations: locked
