Optical interconnects based on optical far- and near-field interactions for high-density data broadcasting.

Ultrahigh-density data-broadcasting optical interconnects are proposed and experimentally demonstrated using optical near-field interactions between quantum dots, which cannot be driven by far-field light, allowing sub-wavelength device operation, and far-field excitation for global interconnects. The proposed scheme helps to solve interconnection difficulties experienced in nano-scale device arrays since components for individually guiding light from external systems are not required. Combining the broadcasting mechanism with switching and summation architectures will allow nano-scale integration of parallel processing devices.
