ABSTRACT:

It is becoming increasingly critical to find new classes of materials that allow for faster and smaller photonic and optoelectronic devices. In this talk we will discuss the quantum optics of a new class of nanomaterials fabricated from graphene, quantum dots and photonic materials. Graphene is a two-dimensional sheet of carbon atoms arranged in a honeycomb lattice. For the first time in 1947 P. R. Wallace from McGill University predicted that graphene is a gapless semiconductor with Dirac points at the Brillouin zone. One-photon and two-photon phenomena such as absorption will be studies in these systems. It is found that system can be switched between the absorption and transparent states. These findings can be applied to develop new types of graphene based nanophotonic devices, such as nano-switches and nano-sensors.
