The logical 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.
||A logical 2x1 reciprocal waveguide coupler.|
||A logical 1x2 reciprocal waveguide coupler.|
||A logical 2x2 reciprocal waveguide coupler.|
The 2x2 logical coupler model parameters can be individually set:
Note that the model does not enforce passivity.
