“…At the shorter wavelength of λ = 2.8 µm, Nanoplus with U. Würzburg observed nearly 1 mW of cw output and 7 nm total tuning range [118]. The same team reported cw single-mode lasing to 0 • C at λ = 5.2 µm [119], and later to 6.0 µm by growing on an InAs substrate [101]. A two-segment grating provided single-mode emission spanning 158 nm, effectively covering the entire ICL gain spectrum, although the tuning was not continuous [120].…”

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.

“…The thresholds for subsequent devices grown at NRC Canada remained low at even longer wavelengths, namely 333 A/cm 2 at λ = 6.0 µm and 395 A/cm 2 at λ = 6.3 µm, for pulsed operation at 300 K [76,99]. The team of U. Würzburg and Nanoplus also demonstrated longer wavelength ICLs grown on InAs substrates [100,101].…”

Compared to the near infrared, many technologically and industrially relevant gas species have more than an order of magnitude higher absorption features in the mid-infrared (MIR) wavelength range. These species include for example important hydrocarbons (methane, acetylene), nitrogen oxides and sulfur oxides. Tunable laser absorption spectroscopy (TLAS) has proven to be a versatile tool for gas sensing applications with significant advantages compared to other techniques. These advantages include real time measurement, standoff detection and ruggedness of the sensor.We present interband cascade lasers (ICLs), which have evolved into important laser sources for the MIR spectral range from 3 to 7 µm. ICLs achieve high efficiency by cascading optically active zones whilst using interband transitions, so they combine common diode laser as well as quantum cascade laser based technologies. Our application grade singlemode distributed feedback devices operate continuous wave at room temperature and are offering several features especially useful for high performance TLAS applications like: side mode suppression ratio of > 30 dB, continuous tuning ranges up to 30 nm, low threshold power densities and low overall power consumption. The devices are typically integrated in a thermoelectrically cooled TO-style package, hermetically sealed using a cap with anti-reflection coated window.This low power consumption as well as the compact size and ruggedness of the fabricated laser sources makes them perfectly suited for battery powered portable solutions for in field spectroscopy applications.

“…Optical methods based on infrared laser spectroscopy for CO 2 and according isotope pairs exploit the pronounced fundamental vibrational band ν 3 of CO 2 in the mid-infrared (MIR) spectral range at 4.3 μm. With advancements in diode laser technology, and thus increasing availability of light sources emitting in the 3–6 μm regime at reasonable output power, interband cascade lasers (ICL) − are of particular interest. ICLs offer emission in the wavelength regime of 3–6 μm at room temperature, provide the required wavelength tunability, and feature low power consumption, as needed for future portable devices.…”

A multiparameter gas sensor based on distributed feedback interband cascade lasers emitting at 4.35 μm and ultrafast electro-spun luminescence oxygen sensors has been developed for the quantification and continuous monitoring of CO/CO isotopic ratio changes and oxygen in exhaled mouse breath samples. Mid-infrared absorption spectra for quantitatively monitoring the enrichment of CO levels were recorded in a miniaturized dual-channel substrate-integrated hollow waveguide using balanced ratiometric detection, whereas luminescence quenching was used for synchronously detecting exhaled oxygen levels. Allan variance analysis verified a CO measurement precision of 1.6‰ during a 480 s integration time. Routine online monitoring of exhaled mouse breath was performed in 14 mechanically ventilated and instrumented mice and demonstrated the feasibility of online isotope-selective exhaled breath analysis within microliters of probed gas samples using the reported combined sensor platform.
