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 article, the performance of the current high speed near infrared HgCdTe sensors operating in fringe trackers, wavefront sensors and tip-tilt sensors is severely limited by the noise of the silicon readout interface circuit (ROIC), even if state-of-the-art CMOS designs are used.

TL;DR: In this paper, it was shown that the readout noise for most arrays is limited by the MBE grown by the HAWAII-2RG material and not by the multiplexer or the data acquisition chain.
