Abstract :
We present the concept and designs of electrostatically-gated graphene infrared (IR) nanodevices for multi-functional biomedical sensing, detection of intracellular bio-events and rotation-vibration absorption, and for polarization sensing and thermal emitters. We exploit the dynamic tunability of the graphene conductivity as a function of gate voltage and the ultralow profile of graphene monolayers to realize tunable nanodevies suitable for chip-scale IR photonic circuit integration.
