Query: Dynamically configurable successively switchable multispectral plasmon
  induced transparency   Plasmon-induced-transparency (PIT) in nanostructures has been intensively
investigated, however, no existing metasurface nanostructure exhibits
all-optically tunable properties, where the number of transparency windows can
be tuned successively, and switched to off-state. Here, we theoretically
investigate and demonstrate dynamically tunable, multichannel PIT at optical
frequencies. The inplane destructive interference between bright and dark
dipolar resonances in coupled plasmonic nanobar topologies is exploited to
produce tunable PIT with unique characteristics. In particular, we demonstrate
sequential polarization-selective multispectral operation whereby the number of
PIT channels can be varied successively from '3' to '0'. The results provide a
promising route for active manipulation of PIT and show potential applications
for multifunctional dynamic nanophotonics devices.
