TL;DR: The High-Acuity Wide-field K-band Imager for ESO's Very Large Telescope (AWK-I) as mentioned in this paper was designed, developed, and performed for the ESO VLSTM.

TL;DR: In this article, the authors developed a near infrared electron avalanche photodiode array (eAPD) for wavefront sensing and fringe tracking. But the array required deep cooling to 40K to achieve acceptable cosmetic performance at high APD gain.

TL;DR: In this paper, the effect of the coupling capacitance between neighboring pixels on the conversion gain of large format arrays has been analyzed and compared quantitatively, and it has been shown that the noise squared versus signal (NoSV) method can only be applied for negligible interpixel capacitance.

TL;DR: SAPHIRA arrays have been used for wavefront sensing and fringe tracking as mentioned in this paper and have achieved state-of-the-art performance in the near infrared near infrared HgCdTe electron avalanche photodiode arrays.

TL;DR: The most promising way to overcome the CMOS noise barrier of infrared AO sensors is the amplification of the photoelectron impedance signal directly at the point of absorption inside the infrared pixel by means of the avalanche gain this paper.
