Photonic applications of graphene

Graphene can be used to enhance photonics, as a detector for light, an optoelectronic transceiver, or as part of high-resolution imaging systems. A surprising application of graphene is its use in photodetectors. Light detection capabilities of graphene are inherently limited because a single sheet of the material absorbs only ~2.3%...

Graphene field-effect transistor (GFET) photodetectors

A surprising application of graphene is its use in photodetectors. Light detection capabilities of graphene are inherently limited because a single sheet of the material absorbs only ~2.3% of light across the visible part of the spectrum. Such high transparency is desired for applications such as transparent conductors, however detecting...

Graphene optical communications gain speed

Optical communication formed the backbone of the internet age and is expected to be equally pivotal for the developing 5G networks. Modern communications rely on optical links that fly information at the speed of light, and on circuitry such as photodetectors and modulators which is able to encode a wealth...

CMOS-compatible high resolution broadband graphene camera

A collaboration between Graphenea and ICFO yielded the world’s first large area graphene-CMOS integrated device. The project built on the team’s expertise in photodetectors to produce a high sensitivity, high resolution camera that captures images from the ultraviolet to the infrared parts of the spectrum. A demonstration of graphene-CMOS integration...

Hybrid graphene – quantum dot infrared photodetectors for food safety

Infrared (IR) thermometry has proven to be an ideal tool for food control inspectors and regulators. A means of measuring food temperature from afar and under versatile conditions, IR thermometers are used to detect food that has started to go bad, improving food quality and increasing productivity. Now, Graphenea and the...
