A high-speed compact silicon modulator based on the lateral capacitor configuration is experimentally demonstrated with low-power consumption and 3 dB modulation depth. The capacitor layout is introduced to scale down the total modulator capacitance to 30 × 10 15 F , which effectively reduces the rf power consumption to 0.54 pJ bit . Exploiting the slow group velocity of light in the slot photonic crystal waveguides, the device reported herein exhibits higher modulation efficiency than conventional capacitor modulator and provides a V π L figure of merit of 0.18 V cm at the wavelength of 1548 nm .
