Claim 0:
1. A structure comprising:
an edge coupler having a longitudinal axis and a facet;
a first waveguide core including a first light absorber;
a second waveguide core including a second light absorber,
a first ring resonator having a first center point that is spaced from the longitudinal axis of the edge coupler by a first perpendicular distance, the first ring resonator positioned adjacent to the first waveguide core; and
a second ring resonator having a second center point that is spaced from the longitudinal axis of the edge coupler by a second perpendicular distance, the second ring resonator positioned adjacent to the second waveguide core,
wherein the first light absorber and the second light absorber each comprise germanium, and the first ring resonator and the second ring resonator are symmetrically placed in a lateral direction transverse to the longitudinal axis of the edge coupler.
