gdsfactory.cross_section.l_with_trenches(width=0.5, width_trench=2.0, width_slab=7.0, layer='WG', layer_slab='WG', layer_trench='DEEP_ETCH', mirror=False, sections=None, **kwargs)[source]#

Return CrossSection of l waveguide defined by trenches.

Parameters:

  • width (float) – main Section width (um) or function parameterized from 0 to 1. the width at t==0 is the width at the beginning of the Path. the width at t==1 is the width at the end.

  • width_trench (float) – in um.

  • width_slab (float) – in um.

  • layer (tuple[int, int] | str | int | LayerEnum) – ridge layer. None adds only ridge.

  • layer_slab (tuple[int, int] | str | int | LayerEnum) – slab layer.

  • layer_trench (tuple[int, int] | str | int | LayerEnum) – layer to etch trenches.

  • mirror (bool) – this cross section is not symmetric and you can switch orientation.

  • sections (tuple[Section, ...] | None) – list of Sections(width, offset, layer, ports).

  • kwargs (Any) – cross_section settings.

Return type:
