Hybrid integration: As metamaterials, nanoplasmonic materials and new kinds of nonlinear optical materials are developed, they need to be integrated with existing optical platforms of silicon or chalcogenide, so that light can pass from one material to another on the same 'chip'.
Hybrid integration involves incorporating metamaterials, nanoplasmonic materials, and novel nonlinear optical materials into existing silicon or chalcogenide optical platforms. This enables light to move between different materials on a single 'chip'.
