Integrated Metamaterial Interfaces for Self-Aligned Fiber-to-Chip Coupling in Volume Manufacturing

Improving the scalability and cost efficiency of photonic packaging is central to fulfilling the silicon photonic promise of low-cost devices with unprecedented optical complexity. A key enabler toward this goal is an efficient, large-mode, integrated fiber coupler and mode converter. Using standard fiber modes at fiber-to-chip junctions avoids expensive in-fiber mode conversion and relaxes alignm...
