An Integrated Array Polarization Imaging Detector Stacked by Multilayer Transparent Black Phosphorus Sheets and the Corresponding Polarization Information Calculation Method

Abstract

The invention discloses an integrated array polarization imaging detector stacked with multi-layer transparent black phosphorus sheets and a corresponding polarization information calculation method. The polarization imaging detector is composed of a plurality of detector units. Each detector unit is composed of three functional layers and a substrate support layer. The functional layer structure uses a transparent black phosphorus sheet as a photosensitive layer and a conductive channel layer, supplemented by electrodes. And protective insulating medium, and add peripheral circuits. Taking the functional layer as the structural unit, stacking multiple layers along the optical path can realize real-time high-resolution polarization detection. When polarized light illuminates the device, due to the characteristics of the black phosphorus sheet itself, only the polarized light along the AC direction (Armchair) of the black phosphorus sheet is absorbed the most, and there will be transmission in other directions, so the stacking structure of black phosphorus sheets with multiple angles , the light intensity information in multiple directions can be obtained by real-time measurement at the same position. The carriers in the black phosphorus sheet move unidirectionally under the driving of an applied potential, generate a response signal and realize the detection of the intensity of polarized light, and solve the target beam information through a specific algorithm. The detector solves the problem of inconsistency in the existing polarization detection space, and has the characteristics of high integration, no resolution loss, and good real-time performance, and is suitable for polarization detection imaging, navigation and other fields.
