Experimental verification of electro-refractive phase modulation in graphene
Muhammad Mohsin, Daniel Neumaier, Daniel Schall +5
Graphene has been considered as a promising material for opto-electronic devices, because of its tunable and wideband optical properties. In this work, we demonstrate electro-refra…
