We report a critical assessment of the use of non-uniform gratings for enhancing light coupling to photonic integrated circuits (PICs). Grating couplers, performing as a very attractive vertical coupling scheme for the silicon waveguide, have been widely demonstrated. It is shown that the coupling efficiency of grating couplers can be enhanced by using an… CONTINUE READING
