Query: Broadband Sub-{\lambda} GHz ITO Plasmonic Mach-Zehnder Modulator on
  Silicon Photonics   Here, we demonstrate a spectrally broadband, GHz-fast Mach-Zehnder
interferometeric modulator, exhibiting a miniscule VpL of 95 V-um, deploying a
sub-wavelength short electrostatically tunable plasmonic phase-shifter, based
on heterogeneously integrated ITO thin films into silicon photonics.
