AutoTransitionPorts¶
- class picazzo3.container.transition_ports.AutoTransitionPorts(*args, **kwargs)¶
Pcell containing another PCell with transitions on all (labeled) ports, using AutoTraceTransitionFromPort. The target trace template is defined in
trace_template
.- Parameters
- trace_template: ( PCell and _WaveguideTemplate ), *None allowed*
Template for all ports, defaults to TECH.PCELLS.WG.DEFAULT.When set to None, the waveguide templates of the ports will be used.
- transition_database: AutoTransitionDatabase
AutoTransitionDatabase in which the correct transition between the two trace templates can be looked up.
- transitions: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>
Transitions (of type WaveguideTransitionFromPort) attached the the ports given in port_labels. Should be in the same order as port_labels.
- port_labels: ( List with type restriction, allowed types: <class ‘str’> ), *None allowed*
Labels of the ports to be processed. Set to None to process all ports.
- contents: PCell
the contents of the container: the child cell
- external_port_names: str
Dictionary for remapping of the port names of the contents to the external ports
- name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters
The unique name of the pcell
- Other Parameters
- trace_templates: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>, locked
list of templates to apply to all ports
Examples
Tapering ports to a wider width:
from technologies import silicon_photonics # noqa: F401 from picazzo3.filters.ring import RingRect180DropFilter from picazzo3.traces.wire_wg import WireWaveguideTemplate my_ring = RingRect180DropFilter() my_ring.Layout() from picazzo3.container.transition_ports import AutoTransitionPorts wire_t = WireWaveguideTemplate() wire_t.Layout(core_width=0.7, cladding_width=0.7 + 2 * 2.0) my_ring_tapered_auto = AutoTransitionPorts( contents=my_ring, port_labels=["W0", "W1", "E0"], trace_template=wire_t ) my_ring_tapered_auto_layout = my_ring_tapered_auto.Layout() my_ring_tapered_auto_layout.visualize(annotate=True)
