The mid-infrared (mid-IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Germanium (Ge)-based photonic integrated circuits in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological substances. Here we review the motivations and the recent developments in this field, from the different material platforms to active and nonlinear devices. We also discuss a few demonstrations of sensing that have already been conducted, attesting the potential applications of such devices. Finally, we conclude by discussing the challenges that have to be solved to transition from lab demonstrations to practical industrial devices.

Based upon significant latent capacity of antimony-containing avalanche photodetectors in comparison with other materials such as Si or GaInAs in certain applications, the material characteristics beginning from ensemble geometric schematics to respective essential features of binary, ternary, and quaternary antimonides, including their applicability and restrictivity, are analyzed and summarized. Under the scope of the separate-absorption–multiplication avalanche photodetector scheme, the options of absorption and multiplication materials mainly concentrated on the benefit of multiplication and coverage of absorption, as well as recommendation of combinations, including grading choices, are discussed. In conjunction with a simple review of previous efforts, overview and prospects on the development of antimonide APDs are presented. Resulting information is also worthy for other types of antimonide devices.

Photodetectors and image sensors, especially in the infrared wavelength regime, are core components of various optical instruments for medical imaging, remote sensing, night vision, and surveillance, etc. The current commercial infrared photodetectors are mostly based on bulk materials including In1- xGaxAs, InSb, Hg1-xCdxTe, etc. Despite continued advancement and high photoelectrical performance, technological factors limit their widespread usage in next-generation photodetectors, especially, the need for cooling, and the high costs associated with the processing of III-V and II-VI semiconductors. Lowdimensional materials, including zero-dimensional (0D) quantum dots, 1D nanowires, and 2D layered materials, with strong lightmatter coupling coefficient, quantum confinement, and ease of heterostructure construction, are emerged as alternative material platforms for high-performance photodetection technologies at room temperature. This article provides a comprehensive review of the technological evolution, contemporary challenges, and future development trends in infrared detector technologies. First, we systematically analyzed the representative materials and technological features of successive generations of infrared detectors. Then, the discussion focuses on advancements in fourth-generation detector technologies, particularly highlighting breakthroughs in multi-dimensional optical information fusion technology encompassing intensity, polarization, spectral, and phase detection. Finally, drawing on application requirements for neuromorphic vision infrared photodetectors that integrate infrared information acquisition, processing, and intelligent decision-making, the review explores transformative development pathways for next-generation infrared detector technologie

Infrared (IR) sensors are widely used in various applications due to their ability to detect infrared radiation. Currently, infrared detector technology is in its third generation and faces enormous challenges. IR radiation propagation is categorized into distinct transmission windows with the most intriguing aspects of thermal imaging being mid-wave infrared (MWIR) and long-wave infrared (LWIR). Infrared detectors for thermal imaging have many uses in industrial applications, security, search and rescue, surveillance, medical, research, meteorology, climatology, and astronomy. Presently, high-performance infrared imaging technology mostly relies on epitaxially grown structures of the smallbandgap bulk alloy mercury–cadmium–telluride (MCT), indium antimonide (InSb), and GaAs-based quantum well infrared photodetectors (QWIPs), contingent upon the application and wavelength range. Nanostructures and nanomaterials exhibiting appropriate electrical and mechanical properties including two-dimensional materials, graphene, quantum dots (QDs), quantum dot in well (DWELL), and colloidal quantum dot (CQD) will significantly enhance the electronic characteristics of infrared photodetectors, transition metal dichalcogenides, and metal oxides, which are garnering heightened interest.
