Distributed Feedback Lasers: 3000 nm - 6000 nm
nanoplus DFB interband cascade laser facilitates new TDLAS applications in mid-infrared
nanoplus offers a DFB interband cascade laser (ICL) at any target wavelength in the mid-infrared (MIR) between 3 μm and 6 μm. The device operates in continuous wave (cw) mode around room temperature. Specifications and behavior are very comparable to a nanoplus laser at lower wavelengths. When you set up an ICL-based analyzer, you can, hence, transfer the engineering knowledge you have gained from building short-wavelength gas sensors.
The nanoplus DFB ICL opens tunable laser absorption spectroscopy (TLAS) for novel MIR applications in industrial gas sensing.
In the 3 μm to 6 μm wavelength window, now covered by interband cascade lasers, many industrially relevant trace gases have their strongest absorption bands. They show absorption strengths that are several orders of magnitude higher than those in other infrared (IR) areas. This concerns prevalent molecules such as carbon dioxide (CO2), nitric oxide (NO) or water (H2O). Most hydrocarbons, e. g. methane, equally locate their topmost absorbing features at these ICL wavelengths.
Using the strongest absorption band of the detected trace gas contributes to
- accelerate the sensing speed
- reduce the noise and
- miniaturize the sensor.
nanoplus ICLs are considered for various progressive applications in industry and research. In the oil and gas sector, they enable accurate process control and support higher energy efficiency and pollutant reduction.
Compared to other sensing techniques, such as gas chromatography, TLAS-based sensors offer the unmatched advantage of real-time analysis.
nanoplus DFB ICL technology outperforms other MIR laser technologies
Different laser technologies have been investigated in recent years to access the 3 μm to 6 μm wavelength range. Besides interband cascade lasers, GaSb-based type I interband diodes and intersubband quantum cascade lasers (QCL) have been a major focus of research.
While GaSb-based type I interband diodes have the disadvantage of decreasing hole confinement and increasing Auger recombination, fast phonon scattering loss impairs the use of intersubband QCLs.
An interband cascade laser, in contrast, uses optical transitions between an electron state in the conduction band and a hole state in the valence band in a cascade of Sb-based type-II QW structures. A broken-gap band edge alignment enables the tailoring of the emission wavelength by altering the cascade structures.
Interband-cascade technology is ideal for high-performance lasing in the entire range from 3 μm to
6 μm due to relatively wavelength-independent threshold powers. It combines high performance with reasonably low power consumption. Like all nanoplus lasers, these devices are manufactured without epitaxial overgrowth, avoiding impairment of ICL performance due to the insertion of patterning-induced defects within the laser layers.

Prism Award Winners 2012
nanoplus DFB interband cascade lasers (ICLs) won the “Prism Award for Green Photonics and Sustainable Energy” in 2012. They cover the entire wavelength range from 3000 nm to 6000 nm. Many prominent gas species have their strongest absorption features in this window. They are now accessible for tunable diode laser spectroscopy in industry and research. SPIE and Photonics Media honored the laser development in a ceremony during Photonics West in San Francisco.
