Abstract
An optical device includes a first plurality of waveguides including a first waveguide and a second waveguide and a multimode waveguide delay comprising a first end and a second end. The first waveguide and the second waveguide are coupled to the first end of the multimode waveguide delay. The first waveguide is coupled to a first optical mode in the multimode waveguide delay. The second waveguide is coupled to a second optical mode in the multimode waveguide delay. The optical device includes a second plurality of waveguides including a third waveguide and a fourth waveguide. The third waveguide and the fourth waveguide are coupled to the second end of the multimode waveguide delay. The third waveguide is coupled to the first optical mode in the multimode waveguide delay. The fourth waveguide is coupled to the second optical mode in the multimode waveguide delay.
