Negative coupling between defects in waveguide arrays

Negative coupling between defects in waveguide arrays

We report on the experimental demonstration of negative coupling constants between defect guides in a waveguide lattice. We find that coupling can only be negative if the defects are negative and an odd number of lattice sites is between the defect guides.
