摘要：
A diffractive coupler coupling light between an opto-electronic element and a waveguide minimizes variation in coupling over an offset range, while providing good coupling efficiency. The offset range may be along the optical axis and/or radial. The diffractive coupler has a long depth of field and no best focus.
