Abstract
QWIP based on the GaAs/AlGaAs material system are commonly used to achieve LWIR FPA. This detector is constrained by the integration charge capacity of conventional integral-readout-reset mode CMOS readout integrated circuits. As a result, the technical specification for the temperature resolution of the infrared detectors, known as NETD, typically ranges from 20 mK to 30 mK. In this paper, we present a 320 × 256 LWIR QWIP FPA, which is formed by bonding quantum well detectors and a pixel-level DROIC. Notably, the NETD achieved by this detector is superior to 5 mK, with the DR exceeding 100 dB, and it operates effectively within a temperature range of 40 K to 80 K, demonstrating excellent adaptability to varying environmental temperatures.
期刊介绍：
The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region.
Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine.
Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
