Abstract :
In this paper appropriate alloys of germanium (Ge) and silicon (Si) have been investigated and applied in silicon-on-insulator (SOI) technology for homogeneous optical sensing at 2.883 μm. Novel vertical slot waveguides have been analyzed, in particular their optimization in order to achieve ultra-high sensitivity as well as relaxed fabrication tolerances. These features have been compared with well-known silicon-based SOI slot waveguides working at 1.55 μm for optical label-free homogeneous sensing.
