“…However, the quantum efficiency of quantum well detectors has always been a difficult problem to overcome. In order to solve this problem, many teams have conducted corresponding research work [1][2][3][4][5][6][7] . Among them, the Arnaud Berurier team has conducted research on 11-14um wide spectral detectors [8] .…”

Quantum well infrared photodetectors (QWIPs) have natural advantages, such as high material maturity and good uniformity. But its low quantum efficiency is often criticized as a drawback. The quantum well optical coupling structure is one of the key factors affecting the quantum efficiency of quantum well detectors. This article mainly focuses on the impact of the optical coupling structure of quantum well detectors on detector wavelength, coupling efficiency, and other aspects. We have established an optical coupling structure model for quantum well detectors, mainly consisting of three different angles of structure structures: 45 degrees, 62 degrees, and 90 degrees periodic two-dimensional diffraction gratings. The 3D-FDTD simulation method was used to simulate the optical coupling structure of quantum well detectors, and the performance indicators of the three structures, such as response wavelength and coupling efficiency, were compared. At the same time, simulations were conducted on different angles of periodic two-dimensional diffraction gratings. It can be seen that as the grating angle increases, the response spectrum width widens, but the amplitude of the response decreases.

The U.S. Army Research Laboratory (ARL) is the Army's premier laboratory for land forces. The Army relies on ARL for scientific discoveries, technological advances, and analyses that enable capabilities a future Army will need to persevere over adversaries. Although a relatively young organization that will celebrate 25 years of the discovery, innovation, and transition of science and technology in October 2017, ARL has already had significant impact in a wide range of scientific and technological disciplines. In this paper, we highlight some of its past and recent achievements in optics and photonics.
