* Plasmonic modulators are high impedance devices. Twice the voltage provided by a 50 Ohm signal source will drop across the plasmonic modulator. Using a DC source or a high impedance matched driver, double the voltage is required to switch the modulator from the on to the off state.

** Operation time of 8000 h with a Vπ degradation < 2.5%.
