Paper Abstract

Several silicon-based plasmonic waveguides are proposed for long propagation and ultrafast all-optical modulation and switching applications. Above-bandgap femtosecond pump pulses are used to generate free carriers in ion-implanted silicon, resulting in ultrafast nonlinear phase and amplitude modulation. It is demonstrated that by carefully designing a 5-layer device from silver, ion-implanted silicon and air, it is possible to achieve long propagation distances (~100μm), or switching times of 5ps and an on-off contrast of 35dB.
