Abstract

In this paper we report on a low energy consumption CMOS-compatible plasmonic modulator based on Franz-Keldysh effect in germanium on silicon. We performed integrated electro-optical simulations in order to optimize the main characteristics of the modulator. A 3.3 dBdB extinction ratio for a 30 μm{\mu}m long modulator is demonstrated under 3 VV bias voltage at an operation wavelength of 1647 nmnm. The estimated energy consumption is as low as 20 fJ/bitfJ/bit.
