                     Abstract:This paper presents an in-depth and comprehensive review of the latest research advancements in InAs/GaSb
                  II-Type superlattice-based multicolor infrared detectors,which are pivotal to a wide range of applications,including night vi-
                  sion,thermal imaging,and remote sensing. The core performance parameters of these detectors are intricately linked to sever-
                  al critical factors,including the meticulous design of their band structure,which governs the electronic transitions and,conse-
                  quently,the spectral response characteristics. This design aspect is crucial for optimizing the detectors' sensitivity and selec-
                  tivity across different infrared wavelength bands. The molecular beam epitaxy (MBE) fabrication process is another corner-
                  stone in the development of high-performance multicolor infrared detectors. Precise control over layer thickness,composition,
                  and interface quality during MBE growth is essential for achieving low dark current,high quantum efficiency,and minimal
                  defects,all of which are vital for enhancing the detectors' overall performance. Beyond these foundational elements,the pa-
                  per also delves into the nuanced aspects of detector performance,such as the management of dark current,which can obscure
                  weak signals,and the optimization of quantum efficiency,which directly impacts the detectors' signal-to-noise ratio. Addi-
                  tionally,the issue of crosstalk between adjacent detector pixels or spectral channels emerges as a significant challenge,partic-
                  ularly in multicolor configurations,where it can degrade spatial resolution and spectral purity. The review systematically ex-
                  amines  the  performance  landscape  of  multicolor  infrared  detectors, encompassing  dual-band  (short/medium, short/long,
                  medium/medium,medium/long,long/long,and long/very long waveband) to tricolor (short/medium/long,medium/long/very
                  long  waveband)  variants.  It  critically  analyzes  the  strengths  and  limitations  of  these  detectors  across  different  spectral
