Abstract

A ne optical interconnect architecture for a 3D switch array using multiple LiNbO₃-based electro-optically modulated gratings in conjunction with substrate guided waves is reported. First the operating mechanism of the system is studied in detail, and the momentum mismatch in the operating process of the system is also demonstrated. Then, a new method for calculating coupling efficiency is derived by introducing a compensation for the mismatch. With the new calculation method and by introducing a substrate guided wave with 45 degree bouncing angle and 100-V applied voltage, an optimized coupling efficiency is obtained even though it is under the case of momentum-mismatch. Finally, the experimental result of coupling efficiency of the electro-optically modulated grating is provided, and agreements between the experimental results and the theoretical prediction are obtained.
