As of today, VIS-NIR voltage tunable image sensors are not available. In these spectral ranges only NIR-enhanced silicon CCD or CMOS arrays or VIS-enhanced InGaAs have been fabricated with multi-band operation eventually obtained by filtering. Much less work has been done in the VIS-NIR bands. Dual band for medium wavelength infrared (MWIR) and long wavelength infrared (LWIR) were previously proposed and demonstrated, with both independent and simultaneous detection and voltage tunability, using arrays of quantum well infrared detectors in III-V compound semiconductors. It is only recently that research efforts have been devoted towards more compact and integrated solutions. Multi-band imagers are typically complex, expensive, bulky they often require multiple exposures and extensive post-processing. This technique has several applications in chemistry, astronomy, biology, medicine and remote sensing (including military and security). It extracts more information with respect to the so-called panchromatic imaging, where pixels record only the total intensity of radiation. Multi-band imaging is a relatively new approach which combines spectroscopic and spatial information. The realization of this simple device will allow in the future the preparation of an image sensor based on silicon with tunable sensitivity between visible and near infrared range for surveillance and security applications. The first goal of this project is to develop a semiconductor voltage-tunable sensor for visible and near-infrared bands integrated on the same chip, fabricated using Germanium on Silicon technology with a novel design of light detecting.
