Parameters:

  • width (float) – in um.

  • layer (tuple[int, int] | str | int | LayerEnum) – for main waveguide section.

  • heater_width (float) – in um.

  • heater_gap (float) – in um.

  • layer_slab (tuple[int, int] | str | int | LayerEnum) – for pedestal.

  • layer_heater (tuple[int, int] | str | int | LayerEnum) – for doped heater.

  • via_stack_width (float) – for the contact.

  • via_stack_gap (float) – in um.

  • layers_via_stack (Sequence[tuple[int, int] | str | int | LayerEnum]) – for the contact.

  • bbox_offsets_via_stack (tuple[float, ...]) – for the contact.

  • slab_gap (float) – from heater edge.

  • slab_offset (float) – over the center of the slab.

  • with_top_heater (bool) – adds top/left heater.

  • with_bot_heater (bool) – adds bottom/right heater.

  • sections (tuple[Section, ...] | None) – list of sections to add to the cross_section.

  • kwargs (Any) – cross_section settings.

Return type:
