摘      要：Reduction of modulator energy consumption to 10 fJ∕bit is essential for the sustainable development of communication *** modulators might be a viable solution if instructed by a complete theory ***,we present a complete analytical electro-optic response theory,energy consumption analysis,and eye diagrams on absolute scales for lumped *** the speed limitation is understood and alleviated by single-drive configuration,and comprehensive knowledge into the energy dependence on structural parameters significantly reduces energy *** results show that silicon modulation energy as low as 80.8 and 21.5 fJ∕bit can be achieved at 28 Gbd under 50 and 10 Ω impedance drivers,respectively.A 50 Gbd modulation is also shown to be *** analytical models can be extended to lumped modulators on other material platforms and offer a promising solution to the current challenges of modulation energy reduction.
