1. An optical device, comprising:
a first waveguide including:
a plurality of first portions coupled with regions doped with first dopants including a respective first portion coupled with a first region doped with first dopants; and
a plurality of second portions coupled with regions doped with second dopants, distinct from the first dopants, the plurality of first portions being interleaved with the plurality of second portions, the plurality of second portions including a respective second portion coupled with a second region doped with the second dopants; and
a second waveguide located adjacent to the first waveguide for coupling light from the first waveguide to the second waveguide, the second waveguide including:
a third portion coupled with a third region doped with the first dopants and a fourth portion coupled with a fourth region doped with the second dopants, wherein the respective first portion is located adjacent to the third portion and the respective second portion is located adjacent to the fourth portion.
