Abstract :
Inter-layer coupling between multilayer waveguides was demonstrated using a hydrogenated amorphous silicon (a-Si:H) grating couplers. The grating couplers consist of two vertically stacked waveguides sandwiched by metal mirrors. An enhancement of the coupling efficiency was observed by introducing metal mirrors.
