This paper demonstrates, via simulation, an electro-optic modulator based on a subwavelength Fabry-Perot resonator cavity with ultra-low power consumption. The device is modulated at a doped p-i-n junction overlapping the cavity in a silicon waveguide perforated with etched holes, with the doping area optimized for minimum power consumption. The surface area of the entire device is only 2.1 mum2....
We demonstrate a 20-/spl mu/m-long tunable optical Fabry-Perot resonator integrated on a silicon-on-insulator waveguide. The device is electrically driven and shows a modulation depth as high as 53% for a power consumption of only 20 mW.
