“…Such a low dependence on bias voltage has already been observed on photocurrent I(V) curves [9] (they were attributed to electric field domain formation under illumination). It also has been observed on dark current, see ref [5], [10] and [11], but to the best of our knowledge, such a plateau behaviour has never been deeply investigated. We underline that the coupling in this QWIP (miniband width of a few ten nanoeV) is particularly weak and we do not expect to be on the same regime of transport as much coupled superlattice [10].…”

Thanks to their wavelength diversity and to their excellent uniformity, Quantum Well Infrared Photodetectors (QWIP) emerge as potential candidates for astronomical or defense applications in the very long wavelength infrared (VLWIR) spectral domain. However, these applications deal with very low backgrounds and are very stringent on dark current requirements. In this paper, we present the full electro-optical characterization of a 15µm QWIP, with emphasis on the dark current measurements. Data exhibit striking features, such as a plateau regime in the I(V) curves at low temperature (4 to 25 K). We show that present theories fail to describe this phenomenon and establish the need for a fully microscopic approach.

“…It is quite amazing that the author's original paper on the planet detection was rejected in the early 90s, because the reviewer considered detection at 18 m something technologically impossible and therefore not worthy of being published. Today, about 20 years later, the detector technology is being developed at an ever-faster rate, covering increasingly longer wavelengths (Boeker et al, 1997;Farhoomand et al, 2006;Martijn et al, 2005, Müller et al, 2010Olsen et al, 1997;Reichertz et al, 2005;Royer et al, 1997;Thomas et al, 1998;Young, 1993). Focal plane architectures are being implemented for cameras, some incorporating bolometers, for far IR / sub-mm spectral range (Agnese et al, 2002;Poglitsch et al, 1997;Wilson et al, 2004).…”

“…Different scenarios are generally mentioned when dealing with low flux applications. Generally they are linked with defence or astronomy [1,14,15,16]. We have chosen an alternative way, which is thermometric imagery for the ETW (European transonic wind tunnel) cryogenic wind tunnel [3].…”

“…According to the Wien law, high wavelength detectors are good candidates for low photon flux detection which is involved in applications such as defence [1], astronomy [2] or cryogenic wind tunnels [3]. QWIPs are well-known to provide high uniformity focal plane arrays (FPAs) with few bad pixels.…”

Abstract:Quantum Well Infrared Photodetector (QWIP) usually suffer from a too moderate quantum efficiency and too large dark current which is often announced as crippling for low flux applications. Despite this reputation we demonstrate the ability of QWIP for the low infrared photon flux detection. We present the characterization of a state of the art 14.5µm QWIP from Alcatel-Thales 3-5 Lab. We developed a predictive model of the performance of an infrared instrument for a given application. The considered scene is a Cryogenic Wind Tunnel (ETW), where a specific Si:Ga camera is currently used. Using this simulation tool we demonstrate the QWIP ability to image a low temperature scene in this scenario. QWIP detector is able to operate at 30K with a NETD as low as 130mK. In comparison to the current detector, the temperature of use is three times higher and the use of a QWIP based camera would allow a huge simplification of the optical part. : 85.60Bt, 85.60Gz PACS
