gdsfactory.path.transition(cross_section1: CrossSectionSpec, cross_section2: CrossSectionSpec, width_type: Literal['sine', 'linear', 'parabolic'] | Callable[[float], float] = 'sine', offset_type: Literal['sine', 'linear', 'parabolic'] | Callable[[float], float] = 'sine') → Transition[source]#

Returns a smoothly-transitioning between two CrossSections.

Only cross-sectional elements that have the name (as in X.add(…, name = ‘wg’) ) parameter specified in both input CrosSections will be created. Port names will be cloned from the input CrossSections in reverse.

Parameters:

  • cross_section1 – First CrossSection.

  • cross_section2 – Second CrossSection.

  • width_type – ‘sine’, ‘parabolic’, ‘linear’ or Callable. type of width transition used if any widths are different between the two input CrossSections.

  • offset_type – ‘sine’, ‘parabolic’, ‘linear’ or Callable. type of width transition used if any widths are different between the two input CrossSections.
