Abstract
Silicon technologies have been developed for both electronics and photonics. Future demands call for further innovation in each field separately, but also depend on our ability to bring the best of both worlds together through integrated solutions. For decades, the pursuit of all-silicon electronic-photonic integration has been hindered by the lack of a native light source due to silicon’s indirect bandgap. Here, we discuss the potential for micro- and nano-scale light sources realized in microelectronic CMOS technology without any modification or postprocessing. High brightness is realized by exploiting the well-passivated silicon surfaces available in CMOS to realize efficient light emission despite the indirect bandgap. NIR emission at the silicon bandgap is demonstrated and exploited to demonstrate chip-to-chip optical links and sensors utilizing only silicon light sources.
