Abstract
The invention relates to short-wave infrared (SWIR) detector arrays, and methods for forming such arrays, comprising a light conversion layer () having a germanium-tin alloy composition. The shortwave infrared (SWIR) detector array comprises an absorber wafer (II) and a readout wafer (I). The absorber wafer (II) comprises a SWIR conversion layer () which has a Gei-xSnalloy composition. The SWIR conversion layer () may have an internal structure comprising an array of rods () extending between a patterned support layer () and a doped silicon layer (). The detector comprises also a readout wafer (I) including an array of charge collecting areas and a readout electric circuit. The readout wafer (I) and the absorber wafer (II) are bonded by a low temperature bonding technique. The invention also relates to methods of fabrication of the SWIR detector array and to SWIR detector array applications such as a multi/hyperspectral LIDAR imaging systems.
