Abstract

Spectral crosstalk suppressing design of two-color HgCdTe medium-wave/long-wave (MW/LW) \(\hbox {n}^{+}\)–\(\hbox {p}_{1}\)–\(\hbox {P}_{2}\)–\(\hbox {P}_{3}\)–\(\hbox {N}^{+}\) infrared focal plane arrays (IRFPAs) detector functioning in simultaneous mode is carried out in this study, using Crosslight Technology Computer Aided Design (TCAD) software. A compositional barrier of \(\hbox {P}_{2}\)-region sandwiched between LW absorption layer of \(\hbox {p}_{1}\)-region and MW absorption layer of \(\hbox {P}_{3}\)-region is designed to suppress spectral crosstalk. MW-to-LW crosstalk can be significantly suppressed to 2.1 % while LW-to-MW crosstalk can be maintained less than 1 % by integrating an optimized compositional barrier.
