Towards Interband Cascade lasers on InP Substrate. [PDF]

Materials (Basel), 2021
In this study, we propose designs of an interband cascade laser (ICL) active region able to emit in the application-relevant mid infrared (MIR) spectral range and to be grown on an InP substrate. This is a long-sought solution as it promises a combination of ICL advantages with mature and cost-effective epitaxial technology of fabricating materials and

Strain mapping in interband cascade lasers [PDF]

AIP Advances, 2022
A typical interband cascade laser wafer contains more than 2000 multilayers composed of InAs, AlSb, GaSb, and GaInSb. The lattice constants of the three materials except GaSb have a certain degree of mismatch with the GaSb substrate. Therefore, to grow a

Dual-gas quartz-enhanced photoacoustic spectroscopy sensor exploiting two fiber-combined interband cascade lasers [PDF]

Photoacoustics
In this work, a novel indium fluoride glass 2-input-1-output fiber combiner was designed and fabricated to combine two Interband Cascade Laser (ICL) sources emitting in the mid-infrared wavelength range.

Substrate-emitting ring interband cascade lasers [PDF]

Applied Physics Letters, 2017
We demonstrate interband cascade lasers fabricated into ring-shaped cavities with vertical light emission through the substrate at a wavelength of λ ≈ 3.7 μm. The out-coupling mechanism is based on a metallized second-order distributed feedback grating. At room-temperature, a pulsed threshold current-density of 0.75 kA/cm2 and a temperature-tuning rate

Greenhouse Gases Detection Exploiting a Multi-Wavelength Interband Cascade Laser Source in a Quartz-Enhanced Photoacoustic Sensor [PDF]

Sensors
This study presents the performance of a multi-gas sensor for greenhouse detection based on quartz-enhanced photoacoustic spectroscopy (QEPAS). The QEPAS sensor exploits an innovative, compact three-wavelength laser module as excitation source.

An interband cascade laser based heterodyne detector with integrated optical amplifier and local oscillator [PDF]

Nanophotonics
Heterodyne detection based on interband cascade lasers (ICL) has been demonstrated in a wide range of different applications. However, it is still often limited to bulky tabletop systems using individual components such as dual laser setups, beam shaping

Long Wavelength Interband Cascade Lasers. [PDF]

Proposed for presentation at the 15th International Conference on Mid-Infrared Optoelectronic Materials and Devices in , ., 2021
InAs-based interband cascade lasers (ICLs) can be more easily adapted toward long wavelength operation than their GaSb counterparts. Devices made from two recent ICL wafers with an advanced waveguide structure are reported, which demonstrate improved device performance in terms of reduced threshold current densities for ICLs near 11 μm or extended ...
