Graphene is an exotic photoelectronic material of choice of this decade. It exhibits unique broadband optical absorption characteristics and metal like transport properties. Graphene's Fermi level coincides with the electron and hole states giving it high charge carriers mobility in excess of 15000 cm2V-1s-1 and electric current density sustenance million times higher than copper. This unique advantage makes the realization of broadband photodetectors possible that far exceeds the capabilities of conventional photodetectors both in bandwidth and responsiveness despite its one-atom layer thickness and has attracted significant interest in photonics applications. Graphene research as such has emerged as a translational nanotechnology bridging academic research to state-of-the-art applications and continues to do so by exploiting these unique properties. Few-layer-graphene (FLG) has also received much attention recently because of its promising bandgap tunability and acute temperature sensitivity. Our proposed research is to take up the challenge of identifying prospective FLG and FLG-composites that exhibit high photo-responsive gain with tunable bandwidth properties that can have a transformative impact in the photonics and imaging sensors industry. The project will delve into developing novel resonance-based FLG-photodetectors and sensors that would also tap on to the global photonics market that is expected to reach $970.5 billions by 2027. We will demonstrate proof-of-concept of developing novel high-gain photoelectronic devices with transparent and flexible form factors. Graphene's unique optical and electrical properties have the potential to make a profound impact in Information and Communications Technology in the short and long term. FLG-components integrated with silicon-based electronics will usher substantial performance improvements supporting huge data loads and enabling completely new applications. In the long run seamlessly integrating photonic devices, sensors, and gadgets into Smart Internet of Things is envisioned.
