Abstract

We design a color router made of a single layer only and show that it achieves very high optical efficiency (> 0.7) and low cross-talk simultaneously, despite being a significant simplification of an ideal color router. Unlike other single-layer approaches, a single-layer color router separates colors directly at its output without additional external propagation. This allows for better performance compared to single-layer approaches that use a propagation distance to separate colors. We illustrate the importance of the non-propagating, near-field contributions to creating highly-efficient color separation devices.
