Abstract
An optical device includes a first waveguide that includes a plurality of first portions coupled with regions 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. And the optical device includes a second waveguide located adjacent to the first waveguide for coupling light from the first waveguide to the second waveguide. The second waveguide includes 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 first portion is located adjacent to the third portion and the second portion is located adjacent to the fourth portion.
