# Generic Waveguide Couplers¶

The generic waveguide couplers allow the transfer of light from one waveguide port to another. The couplers are only implemented at a logical level (circuit model) without any layout implementation. They can be used for circuit design and serve as the basis for actual implementations such as directional couplers.
