Linear taper, which tapers only the main cross section section.

Parameters:

  • length – taper length.

  • width1 – width of the west/left port.

  • width2 – width of the east/right port. Defaults to width1.

  • port – can taper from a port instead of defining width1.

  • with_two_ports – includes a second port. False for terminator and edge coupler fiber interface.

  • cross_section – specification (CrossSection, string, CrossSectionFactory dict).

  • port_names – input and output port names. Second name only used if with_two_ports.

  • port_types – input and output port types. Second type only used if with_two_ports.

  • with_bbox – box in bbox_layers and bbox_offsets to avoid DRC sharp edges.

  • kwargs – cross_section settings.
