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

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.

• with_loopback_inside – True, adds loopback structures inside the component.

• 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.

• radius – optional radius of the bend. Defaults to the cross_section.

• radius_loopback – optional radius of the loopback bend. Defaults to the cross_section.

• route_backwards – route from component to grating coupler or vice-versa.
