Abstract

We present, for the first time, solution processed colloidal quantum dot extended short wavelength infrared (eSWIR) 1920 x 1080 format cameras sensitive from 300 nm to 2100 nm wavelengths at a pitch of 15 microns. We describe the performance of this high-definition imager using EMVA1288 machine vision testing and demonstrate pixel detectivities of 1 x10¹² Jones and 32 fA of dark current when operating at room temperature [1]. These results show this monolithically integrated detector technology has sensitivity superior to most traditional epitaxial IR sensors employed in the 1700 to 2100 nm band [2]. The straightforward and scalable fabrication processes employed have enabled the first commercially available room temperature 2.1 MP camera with sensitivity out to 2.1 um.
