Photonics and Optoelectronics
Work Package 8
Photonics is the science of light. It is the study of the wave and particle properties of photons, and the technology to generate, control and detect them. Optoelectronics is a sub-field of photonics, focusing on the theory, design and applications of electronic devices that interact with light.
Thanks to its unique optical and electronic properties, graphene is a rising star in the field, with many applications in solar cells, light-emitting devices, touch screens, long-range communication devices and ultrafast lasers. In the Graphene Flagship’s Photonics and Optoelectronics Work Package, our mission is to use graphene and layered materials to develop components and integrated systems for applications like these.
Putting Graphene to the test
In our Work Package, we benchmark every component against existing technologies. We only target industrial applications, and using graphene, we have a very strong potential for innovation. Photonics and optoelectronics technologies have unique advantages compared to existing technology, and the market demand is very clear.
For instance, graphene integrated with a silicon-based complementary metal–oxide–semiconductor (CMOS) circuit shows a strong advantage in terms of performance over non-silicon-based semiconductors that are not easily integrated into Si-CMOS technology. This enables much lower-cost imaging systems, such as cameras, that can detect light over a much broader range of wavelengths.
Moreover, our optoelectronic components for data communications devices require significantly less power than commercial technologies. Data transfer rates are growing exponentially over time, so our energy-efficient devices will be critical to ensure the next generation of computing is both technologically feasible and environmentally sustainable.
