Abstract
The 2-2.5 m region of the electromagnetic spectrum is of particular importance for the non-invasive monitoring of blood glucose using absorption spectroscopy, since it can provide the strongest signature as compared to other water transmission windows. Currently available spectroscopy systems for this application require high-gain and low-noise detectors in order to achieve sufficient signal-to-noise ratio measurements. In this context, we are investigating the integration of micro-optics along with InGaAsSb/AlGaAsSb avalanche photodetectors in order to demonstrate high-fill factor, high quantum efficiency and eventually the ability to evaluate the blood glucose concentration with high accuracy. Also, using the bandgap engineering options afforded by the quaternary antimonide structures, the spectral response of the detector can be tuned over this wavelength range. In this paper, we present the design, fabrication and integration of the multi-chip modules, the constituent technologies required to realize them and experimental results from their characterization.
