Two- and three-dimensional studies of a Silicon-based Chromatic Dispersion Compensator

摘要

In this work, we demonstrate two- and three-dimensional (3D) simulations of an active silicon-based photonic crystal chromatic dispersion compensator utilizing the free carrier dispersion effect. The device has a low power consumption of 114nW and its intrinsic device modulation speed is predicted to function at 40.5MHz. Due to the device architecture, simulation must be carried out in 3D so as to fully encapsulate the effects of the photonic crystal contributions in the active silicon. The novel device allows waveguiding and electrical transport to be individually tailored to a large extent.
