Abstract
An optical coupling system is provided which includes a first layer structure and a second layer structure. The first layer structure includes a plurality of layers sequentially stacked on a substrate, and is configured to compresses a beam emitted from a light source along a direction substantially perpendicular to a top surface of the substrate. The second layer structure is formed on the substrate, and is configured to compresses the beam, having passed through the first layer structure, along a direction substantially parallel to the top surface of the substrate.
