Abstract

Research on mid-IR silicon-based waveguides has recently received strong interest. This paper focuses on optical integration between a broadband LED mid-infrared light source and micro-scale optical waveguide. The optical coupling scheme is crucial for the exploitation of LED light sources in waveguide-based spectroscopic sensing applications. Optical simulations based on Eigen Mode Expansion (EME) and FDTD methods is used to obtain approximate and optimized parameters. The sensitivity of the optical sensors will be evaluated with respected to the required optical power at the optical sources. The ability to efficiently couple light from a LED light source into a micron-scale waveguide could be beneficial for a wide range of application that is cost-sensitive.
