gdsfactory.routing.add_fiber_array.add_fiber_array(component: ComponentSpec = <function straight>, grating_coupler: ComponentSpecOrList = functools.partial(<function grating_coupler_elliptical_trenches>, polarization='te', taper_angle=35), gc_port_name: str = 'o1', component_name: str | None = None, select_ports: Callable = functools.partial(<function select_ports>, port_type='optical'), cross_section: CrossSectionSpec = 'strip', taper: ComponentSpec | None = None, **kwargs) Component[source]#

Returns component with south routes and grating_couplers.

You can also use pads or other terminations instead of grating couplers.

Parameters:
  • component – component spec to connect to grating couplers.

  • grating_coupler – spec for route terminations.

  • gc_port_name – grating coupler input port name.

  • component_name – optional for the label.

  • select_ports – function to select ports.

  • cross_section – cross_section function.

  • taper – taper spec.

  • kwargs – additional arguments.

Keyword Arguments:
  • bend – bend spec.

  • straight – straight spec.

  • fanout_length – if None, automatic calculation of fanout length.

  • max_y0_optical – in um.

  • with_loopback – True, adds loopback structures.

  • straight_separation – from edge to edge.

  • list_port_labels – None, adds TM labels to port indices in this list.

  • connected_port_list_ids – names of ports only for type 0 optical routing.

  • nb_optical_ports_lines – number of grating coupler lines.

  • force_manhattan – False

  • excluded_ports – list of port names to exclude when adding gratings.

  • grating_indices – list of grating coupler indices.

  • routing_straight – function to route.

  • routing_method – route_single.

  • optical_routing_type – None: auto, 0: no extension, 1: standard, 2: check.

  • gc_rotation – fiber coupler rotation in degrees. Defaults to -90.

  • input_port_indexes – to connect.

  • fiber_spacing – in um.
