Abstract
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.
