Abstract

In this paper, results from the development of InAs/GaSb superlattice focal plane arrays (FPAs) at IRnova will be presented. A versatile and robust detector design is used that allows for adjustment of the detection cut-off wavelength from 2.5 mu m up to 14.5 mu m with only minor changes in the detector design. Performance of the fabricated detectors has been reviewed in terms of external quantum efficiency (EQE), dark current and noise for three designs with cut-off wavelengths of 4, 5.5 and 11 mu m at 80 K (referred to as DEEP BLUE, RED HOT and VLWIR, respectively). Measurements on the 15 mu m sized photodiodes demonstrated 70 % EQE for the MWIR designs, and almost 40 % for VLWIR. At the same time, the dark current stayed close to the Rule07 benchmark for all studied samples. Noise mechanisms have been discussed and their relation to the passivation was examined. Mature in-house processing and passivation technique resulted in very high spatial uniformity of VGA focal plane arrays (FPAs), i.e. low relative deviations of EQE (< 6 %) and of dark current density (< 12 %), and narrow noise distributions for both RED HOT and DEEP BLUE FPAs. We show also that >99.5 % of these arrays operate close to the fundamental noise limit., QC 20202021

Abstract

Herein, a model is developed to study the polarization‐selective light‐coupling in quantum well infrared photodetector arrays with 15 and 30 μm pixel pitch. The polarization‐selective light‐coupling is achieved using 1D lamella gratings with varying grating orientation and studied through 2D and 3D finite‐element method simulations. The extracted absorption quantum efficiency ηabs, derived from the field distribution, shows excellent agreement with experimental data in terms of absorption peak position for both pitch sizes. Several factors impacting the simulated absorptance level are discussed and a good agreement between the simulation and measured ηabs is achieved. Thanks to the developed 3D model, the polarization‐selective light‐coupling in pixels with 0° and 45° grating orientation is explored. The developed model paves the way for future studies on enhanced light‐coupling in small pitch infrared detectors using resonance structures. [ABSTRACT FROM AUTHOR]
