“…Although high spectral purity is typically not needed for this application, substantial cw output powers are essential. Other potential applications of mid-IR sources include industrial process control [2], combustion diagnostics [3], clinical breath analysis [4], isotope differentiation [4], free space optical communications [5], IR scene projection [6], and the detection of explosives [7].…”

We review the history, development, design principles, experimental operating characteristics, and specialized architectures of interband cascade lasers for the mid-wave infrared spectral region. We discuss the present understanding of the mechanisms limiting the ICL performance and provide a perspective on the potential for future improvements. Such device properties as the threshold current and power densities, continuous-wave output power, and wall-plug efficiency are compared with those of the quantum cascade laser. Newer device classes such as ICL frequency combs, interband cascade vertical-cavity surface-emitting lasers, interband cascade LEDs, interband cascade detectors, and integrated ICLs are reviewed for the first time.

“…can modulate the intensity distribution by changing the reflection or transmission of the infrared radiation. Among these technologies, light emitting diode needs ultra-low operating temperature (77 K) and laser diode array suffers from severe deposition heat and narrow radiation band [24,25]. IR liquid crystal light valve has limitations in frame rate, temperature range and dynamic range [26].…”

A robust micro-electro-mechanical systems (MEMS) infrared thin film transducer of an ultra-large-scale array was proposed and fabricated on a 4-inch silicon wafer. The silicon substrate and micro cavities were introduced. This novel transducer had excellent mechanical stability, time response, and state-of-the-art pixel scale. It could bear a load of 1700 g and its load pressure was improved by more than 5.24 times and time constant decreased by 50.7% compared to the traditional soft infrared thin film transducer. The array scale of its pixels exceeded 2k × 2k. The simulation and measured results of the transient temperature and radiation intensity were well consistent. Illuminated by a 532 nm laser with a frequency of 50 Hz and 50% duty cycle, the thermal decay time of the proposed transducer was 6.0 ms. A knife-edge image was utilized for spatial resolution test and the full width at half maximum (FWHM) of the proposed transducer was 24% smaller than the traditional soft one. High-resolution infrared images were generated using the proposed robust transducer. These results proved that the robust transducer was promising in infrared image generation.

“…In order to facilitate testing of IR detectors in laboratory environments, infrared scene projectors (IRSPs) have been developed to simulate real-time IR scenes. By overcoming the limitations of costly, risky, and time-consuming field tests, IRSPs have accelerated the development of IR detectors [1,2,3]. At the same time, these improved detectors have driven the demand for high-temperature and high-speed IRSPs capable of accurate testing and evaluation of the detectors' performance.…”

This letter presents a mismatch-tolerant read-in integrated circuit (RIIC) with voltage-drop compensation applicable to high-speed and hightemperature infrared scene projectors. A current-programmed unit pixel is designed to compensate for ground-line voltage drops, thus improving the array-wide current uniformity. The proposed mismatch-tolerant design circumvents non-monotonic fluctuations in the output current, irrespective of the matching properties of sampling capacitors and switches. A prototype RIIC with a 32 × 32 unit-pixel array is fabricated in a 0.18-µm CMOS process. The RIIC compensates for voltage drops up to 500 mV with error currents below 1 µA and achieves 10-bit accuracy with output-current nonmonotonicity eliminated.
