gdsfactory.Component

class gdsfactory.Component(name: str | None = None, kcl: KCLayout | None = None, kdb_cell: Cell | None = None, ports: Ports | None = None)

Canvas where you add polygons, instances and ports.

• stores settings that you use to build the component

• stores info that you want to use

• can return ports by type (optical, electrical …)

• can return netlist for circuit simulation

• can write to GDS, OASIS

• can show in KLayout, matplotlib or 3D

Properties:

info: dictionary that includes derived properties, simulation_settings, settings (test_protocol, docs, …)

__init__(name: str | None = None, kcl: KCLayout | None = None, kdb_cell: Cell | None = None, ports: Ports | None = None) → None
