  We show that the Higgs mode of a superconductor, which is usually challenging
to observe by far-field optics, can be made clearly visible using near-field
optics by harnessing ultraconfined graphene plasmons. As near-field sources we
investigate two examples: graphene plasmons and quantum emitters. In both cases
the coupling to the Higgs mode is clearly visible. In the case of the graphene
plasmons, the coupling is signaled by a clear anticrossing stemming from the
interaction of graphene plasmons with the Higgs mode of the superconductor. In
the case of the quantum emitters, the Higgs mode is observable through the
Purcell effect. When combining the superconductor, graphene, and the quantum
emitters, a number of experimental knobs become available for unveiling and
studying the electrodynamics of superconductors.
