Paper Abstract

Surface relief gratings with tilted grating profiles have been studied for efficient optical signal coupling for polymeric waveguide based optoelectronic interconnects. In this article the theoretical formulation used to calculate the diffraction efficiency in a pre-defined direction is discussed. The designed gratings provide an effective unidirectional surface-normal optical coupling for polymer-based optoelectronic interconnects. The gratings with a tilt-angle of 32 degrees and periods ranging from 0.5 to 3 micrometers were fabricated. Both surface-normal input and output grating couplers have been demonstrated in polyimide waveguides on silicon substrate.
