Figure 4: Integrated nanophotonic link.
From: Nanophotonic integrated circuits from nanoresonators grown on silicon

(a) SEM image of a nanophotonic link on silicon constructed from nanoresonator devices. The insets show top-view optical images of a single nanoresonator LED and its emission. The optical links clearly and robustly transmit data under both (b) dc operation and (c) ac operation. All link measurements were performed at room temperature.
