摘要

A simple method improving grating couplers’ coupling efficiency without any extra micro fabrication processes is proposed. This method can improve the coupling efficiency with 1.69dB by utilizing the combined interference in cladding layer and air gap between the cladding surface and the paralleled angle polished fiber facet. The proposed method can be applied to various kinds of on-chip grating couplers. Back reflection, 1-dB bandwidth and fiber alignment tolerance has been also improved at the same time.
