Abstract
A connected optical waveguide structure comprises n four-port optical couplers, where n is greater than one; and n waveguide loops, each loop having a corresponding perimeter; wherein each of the n perimeters is different from each of the other n−1 perimeters. In one embodiment, for any pair of the n loops, the ratio of the larger perimeter to the smaller perimeter is greater than five halves (5/2).
