Acuros® CQD® sensors are fabricated via the deposition of quantum dot semiconductor crystals upon the surface of silicon wafers. The resulting CQD photodiode array enables high resolution, small pixel pitch, broad bandwidth, low noise, and low inter-pixel crosstalk arrays, eliminating the prohibitively expensive hybridization process inherent to InGaAs sensors. CQD sensor technology is silicon wafer-scale compatible, opening its potential to very low-cost high-volume applications.

SWIR Vision Systems to release industry-leading 6 MP SWIR sensors for defense, scientific, automotive, and industrial vision markets
 
The company’s latest innovation, the Acuros® 6, leverages its pioneering CQD® Quantum Dot image sensor technology, further contributing to the availability of very high resolution and broad-band sensors for a diversity of applications.

Durham, N.C., October 31, 2023 – SWIR Vision Systems today announces the upcoming release of two new models of short-wavelength infrared (SWIR) image sensors for Defense, Scientific, Automotive, and Industrial Users. The new sensors are capable of capturing images in the visible, the SWIR, and the extended SWIR spectral ranges. These very high resolution SWIR sensors are made possible by the company’s patented CQD Quantum Dot sensor technology.

SWIR Vision’s new products include both the Acuros 6 and the Acuros 4 CQD SWIR image sensors, featuring 6.3 megapixel and 4.2 megapixel global shutter arrays. Each sensor has a 7-micron pixel-pitch, 12-bit digital output, low read noise, and enhanced quantum efficiency, resulting in excellent sensitivity and SNR performance for a broad array of applications.

The new products employ SWIR Vision’s CQD photodiode technology, in which photodiodes are created via the deposition of low-cost films directly on top of silicon readout ICs. This approach enables small pixel sizes, affordable prices, broad spectral response, and industry-leading high-resolution SWIR focal plane arrays.

SWIR Vision is now engaging global camera makers, automotive, industrial, and defense system integrators, who will leverage these breakthrough sensors to tackle challenges in laser inspection and manufacturing, semiconductor inspection, automotive safety, long-range imaging, and defense.
“Our customers challenged us again to deliver more capability to their toughest imaging problems. The Acuros 4 and the Acuros 6 sensors deliver the highest resolution and widest spectral response available today,” said Allan Hilton, SWIR Vision’s Chief Product Officer. “The industry can expect to see new camera and system solutions based on these latest innovations from our best-in-class CQD sensor engineering group”.

About SWIR Vision Systems – SWIR Vision Systems (www.swirvisionsystems.com), a North Carolina-based startup company, has pioneered the development and introduction of high-definition, Colloidal Quantum Dot (CQD® ) infrared image sensor technology for infrared cameras, delivering breakthrough sensor capability. Imaging in the short wavelength IR has become critical for key applications within industrial, defense systems, mobile phones, and autonomous vehicle markets.

NIT SWIR camera based on HgTe quantum cascade detector

Image Sensors World        Go to the original article...

The Institute of Nano Sciences from CNRS-Sorbonne University is currently researching and producing quantum dot materials of HgTe, sensitive in the extended SWIR wavelength range. Through a partnership with NIT, a first sensor-camera was produced.

This technology is promising to design low-cost and small pixel pitch focal plane array, as well as to expand the spectral range of the SWIR camera up to 2.5 µm.

This collaborative program is funded by the French National Research Agency.

This video  presents the technology of quantum cascade detector (QCD) deposition with response up to 2um on NIT ROIC’s, and sample results images in various conditions.




A related paper titled "Photoconductive focal plane array based on HgTe quantum dots for fast and cost-effective short-wave infrared imaging" is in the June 2022 issue of Nanoscale journal.

Abstract: HgTe nanocrystals, thanks to quantum confinement, present a broadly tunable band gap all over the infrared spectral range. In addition, significant efforts have been dedicated to the design of infrared sensors with an absorbing layer made of nanocrystals. However, most efforts have been focused on single pixel sensors. Nanocrystals offer an appealing alternative to epitaxially grown semiconductors for infrared imaging by reducing the material growth cost and easing the coupling to the readout circuit. Here we propose a strategy to design an infrared focal plane array from a single fabrication step. The focal plane array (FPA) relies on a specifically designed readout circuit enabling in plane electric field application and operation in photoconductive mode. We demonstrate a VGA format focal plane array with a 15 μm pixel pitch presenting an external quantum efficiency of 4-5% (15 % internal quantum efficiency) for a cut-off around 1.8 μm and operation using Peltier cooling only. The FPA is compatible with 200 fps imaging full frame and imaging up to 340 fps is demonstrated by driving a reduced area of the FPA. In the last part of the paper, we discuss the cost of such sensors and show that the latter is only driven by labor costs while we estimate the cost of the NC film to be in the 10-20 € range.

Image Sensors World        Go to the original article...

Krister Shalm of National Institute of Standards and Technologies presented a tutorial: Single-photon detectors at the 2013 QCrypt Conference in August. http://2013.qcrypt.net

This is from a while back but an excellent educational resource nevertheless!

The video is roughly 90-minutes long but has several gaps that can be skipped ahead. Or play it at >1x speed!
