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.

• gc_port_labels – grating coupler list of labels.

• io_rotation – fiber coupler rotation in degrees. Defaults to None.

• component_name – optional for the label.

• select_ports – function to select ports.

• cross_section – cross_section function.

• get_input_labels_function – function to get input labels. None skips labels.

• layer_label – optional layer for grating coupler label.

• dev_id – device if if we want to add a visible label for the device.

• text – optional componentSpec to generate the text for the dev_id

• id_placement – placement of the id. “c” = center (in between the center grating couplers) “r” = right of the right-most gc “l” = left of the left-most gc “s” = center and below the gc in y

• id_placement_offset – offset for the id placement.

Keyword Arguments:

• bend – bend spec.

• straight – straight spec.

• taper – taper spec.

• get_input_label_text_loopback_function – function to get input label test.

• get_input_label_text_function – for labels.

• 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 – get_route.

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

• input_port_indexes – to connect.

• fiber_spacing – in um.

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