All-optical generation of surface plasmons in graphene

The strong confinement of plasmons in graphene makes them interesting for practical applications, but also difficult to excite. An all-optical technique can excite plasmons in graphene over a range of frequencies. Surface plasmons in graphene offer a compelling route to many useful photonic technologies1,2,3. As a plasmonic material, graphene offers several intriguing properties, such as excellent electro-optic tunability4, crystalline...
