Abstract

In this paper we will describe the fabrication and characterization of passive waveguides which exploit the phenomenon of variable charge state mediation of deep-levels in silicon to vary optical absorption. Silicon waveguides are doped with either thallium or indium and co-doped with phosphorus. Optical absorption is reduced s phosphorus doping is increased. These results suggest a novel method of modulation via charge-state control of the deep-level.
