Electro-optically induced absorption in alpha-Si:H/alpha-SiCN waveguiding multistacks.
Electro optical absorption in hydrogenated amorphous silicon (proportional-Si:H)--morphous silicon carbonitride (proportional-SiCxNy) multilayers have been studied in two different planar multistacks waveguides. The waveguides were realized by plasma enhanced chemical vapour deposition (PECVD), a technology compatible with the standard microelectronic processes. Light absorption is induced at lambda = 1.55 microm through the application of an electric field which induces free carrier accumulation across the multiple insulator/semiconductor device structure. The experimental performances have been compared to those obtained through calculations using combined two-dimensional (2-D) optical and electrical simulations.
