Query: Light-matter interactions in chip-integrated niobium nano-circuit arrays
  at optical fibre communication frequencies   The interplay between electronic properties and optical response enables the
realization of novel types of materials with tunable responses. Superconductors
are well known to exhibit profound changes in the electronic structure related
to the formation of Cooper pairs, yet their influence on the electromagnetic
response in the optical regime has remained largely unstudied. Photonics
metamaterials offer new opportunities to enhance the light-matter interaction,
boosting the influence of subtle effects on the optical response. The
combination of photonic metamaterials and superconducting quantum circuits will
have the potential to advance quantum computing and quantum communication
technologies. Here, we introduce subwavelength photonic nano-grating circuit
arrays on the facet of niobium thin films to enhance light-matter interaction
at fiber optic communication frequencies. We find that optical resonance shifts
to longer wavelengths with increasing nano-grating circuit periodicity,
indicating a clear modulation of optical light with geometrical parameters of
the device. Next to the prominent subwavelength resonance, we find a second
feature consisting of adjacent dip and peak appears at slightly shorter
wavelengths around the diffraction condition Py= lambda, corresponding to the
Wood and Rayleigh anomalies of the first order grating diffraction. The
observed tunable plasmonic photo-response in such compact and integrated
nano-circuitry enables new types of metamaterial and plasmonics-based
modulators, sensors, and bolometer devices.
