Interband Cascade Laser

Detecting the strongest absorption bands in the mid-infrared

DFB Interband Cascade Lasers

nanoplus DFB ICLs for 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 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, TDLAS-based sensors offer the unmatched advantage of real-time analysis.

Applications
CO2 and NOx
Emission control of exhaust fumes: CO2 and NOx

Guided by environmental policies, the automobile industry is concerned to reduce the carbon footprint of vehicles. Automotive suppliers develop innovative combustion engines to control CO2 and NOx concentration in exhaust fumes.

[ 115 ]
NOx
Monitoring of breath gas: NOx

The field of breath analysis considers NOX as a biomarker for asthma and other pulmonary diseases. This new technology becomes more established for clinical applications. It is a cost-effective and non-invasive method of diagnosis and treatment monitoring.

[ 116 , 49 ]
C2H6 and C2H2
Monitoring of breath gas: C2H6 and C2H2

Medical breath analysis considers ethane and acetelyne as a biomarkers for asthma, schizophrenia or lung cancer. The research field of breath analysis uses methane as a biomarker for intestinal problems.

[ 10 ]
NOx
Emission control of flue gases: NOx

NOx is produced during fuel combustion at power plants and other industrial facilities. When it reacts with SO2 it causes acid rain. For this reason NOx and SO2 emissions are restricted and need to be monitored.

[ 67 ]
C2H6
Emission control by methane source identification: C2H6

Ethane is a by-product of methane emissions. The ethane ratio varies between methane emissions from thermogenic and biogenic sources. This allows differentiating oil and gas reserves from those of livestock, landfills, wetlands or stagnant water. Studies are executed on behalf of the US Environmental Protection Agency to quantify methane emissions caused byincreased natural gas exploration and production in the US. A newly developed ethane spectrometer delivers 1 second ethane measurements with sub-ppb precision in an ethane-methane mixture.

[ 61 ]
CH4
Emission control of greenhouse gases: CH4

Greenhouse gas effects and climate change have triggered global emission monitoring of pollutants like methane. Methane is one of the Earth’s most important atmospheric gases. It is, to a large extend, responsible for the accelerating greenhouse effect. The global warming potential of methane is about 30 times higher than that of CO2 based on a 100 year scale. Studies are executed on behalf of the US Environmental Protection Agency to quantify the methane emissions caused by the increased natural gas exploration and production in the US.

[ 162 , 146 , 142 , 141 , 129 , 128 , 119 , 109 , 107 , 92 , 61 ]
C2H6
Emission control of greenhouse gases: C2H6

Ethane is an important greenhouse gas that has a critical impact on climate change. Emissions are related to fossil fuel and biofuel consumption, biomass combustion and natural gas losses. Trace gas detection of ethane is an important tool to monitor greenhouse gases.

[ 146 , 145 , 128 , 119 , 10 ]
CH4
Leakage control in gas pipelines: CH4

Leaks of CH4 may cause dangerous situations and are hard to locate precisely. Hence, maintenance of underground pipelines produces high costs. CH4 leaks are also an important source for greenhouse gases. With TDLS a strong tool is available to manufacture portable leak detectors.

[ 162 ]
CH4
Combustion control in integrated gasification fuel cell cycles: CH4

Methane content of syngas is controlled to improve combustion efficiency of integrated gasification fuel cell cycles.

[ 35 ]
CO2 and CH4
Combustion control in high temperature processes: CO2 and CH4

Continuous monitoring of contents like CO2 or CH4 concentrations is essential for the efficiency of high-temperature processes in e. g. incinerators, furnaces or petrochemical refineries. Managing the CO2 content in combustion processes simultaneously reduces greenhouse gas emissions. This is also relevant for energy generating industries like coal burning power plants.

Award Winning Technology

TDLAS in the mid-infrared

DFB Interband Cascade Laser 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.
