  Control of components in integrated photonic circuits is crucial in achieving
programmable devices. Operation bandwidth of a plasmonic device cannot be
generally tuned once it is manufactured, especially in the visible regime.
Here, we demonstrate the electrical control of such a device for extraordinary
optical transmission~(EOT) in the visible regime. (i) Operation frequency of
the EOT device can be tuned via a bias voltage applied through nanowires. (ii)
Or, at a given frequency, the EOT signal (normalized to the incident field) can
be tuned continuously, e.g., between $10^{-4}$ and $0.4$. This corresponds to a
3-orders of magnitude modulation depth. We utilize Fano resonances induced by a
quantum emitter~(QE) that is embedded into the nanoholes. The external
bias-voltage tunes QE's resonance. We also discuss the lifetime extensions of
surface plasmon polaritons as a response to an ultra-short optical pulse. Our
proposed method provides the active electronic control of EOT signal which
makes it a feasible and compact element in integrated photonic circuits, for
bio-sensing, high resolution imaging, and molecular spectroscopy applications.
