Shortwave IR (SWIR) sensors made using colloidal quantum dot photodiodes offer CMOS-like opportunities for highly scalable, small pixel pitch sensors, owing to their straightforward, monolithic integration with silicon circuitry. SWIR Vision Systems began to realize this potential when it introduced its 2.1 MP Acuros cameras to the industrial, scientific, and commercial imaging markets in 2018. Other opportunities for this detector technology can be found in the need for new sensor technologies in the development of cost and resolution scalable direct time of flight depth sensing systems for consumer and automotive applications. But to realize this potential, this relatively new detector system must also be shown to meet thermal and environmental conditions found in consumer and automotive devices. This paper will provide an overview of the performance of our high definition sensors; and show <3 ns rise/fall time results from testing the response time of the photodiode structure using a pulsed laser sources. It will also present data demonstrating stable device operation at elevated temperature and humidity conditions.
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.
