Germanium on Silicon dual-detector for solvent recognition
Controlling the spectral response of optical devices is highly desired for several sensing applications. Herein we present a voltage tunable Ge-on-Si dual-band photodetector capable to sense from visible to short-wave infrared ranges. The device results from the junction of a Si and Ge photodiodes in a back-to-back configuration which enables the pixel level data acquisition under the same experimental conditions, allowing the information combination from the visible and infrared bands, enhancing the imaging and sensing applications.
