Abstract
Here, we propose the usage of dual-interface grating (DIG) supercells with multiperiodicity as shown in Fig. 1(c) and numerically study their extensive mode-coupling possibilities. We consider a-Si solar cell systems which have active layer thickness that is comparable to the size of the grating geometry. At such thickness regime, the grating structure heavily affects the eigenfield profiles of the guided modes. We show how DIG supercells offer much possibility in improving higher order diffraction coupling conditions to guided modes, while maintaining lower order diffraction coupling efficiency. In addition, including symmetry-breaking or blazing properties in DIG structures can lead to excite previously inaccessible modes efficiently, and thus further broadens the enhancement range.
