Physics of interband cascade lasers

SPIE Proceedings, 2012
The interband cascade laser (ICL) is a unique device concept that combines the effective parallel connection of its multiple-quantum-well active regions, interband active transitions, and internal generation of electrons and holes at a semimetallic interface within each stage of the device. The internal generation of carriers becomes effective under

Mid-IR interband cascade lasers

Conference Proceedings. LEOS '97. 10th Annual Meeting IEEE Lasers and Electro-Optics Society 1997 Annual Meeting, 1997
The multi-stage interband cascade laser (ICL) represents a fundamentally new class of semiconductor coherent IR source. Numerical simulations predict that it will combine the advantages of low threshold currents, high operating temperatures, and high output powers at wavelengths from 2.5 /spl mu/m to 7 /spl mu/m.

High-Brightness Interband Cascade Lasers

CLEO: 2015, 2015
Mid-IR interband cascade lasers will be reviewed. Advantages include 3–6 μm spectral coverage, wallplug efficiency up to 18% when operated in cw mode at ambient temperature, and ultra-low threshold drive power.

Interband cascade distributed-feedback lasers

SPIE Proceedings, 2007
Significant recent advances in the high-temperature, high-power performance of type-II antimonide interband cascade lasers (ICLs) operating in the mid-infrared are reported. A 5-stage ICL with a 12-mm ridge width and Au electroplating for improved epitaxial-side-up heat sinking operates cw to a maximum temperature of 257 K, where the emission ...

Mid-IR Interband Cascade Lasers

MRS Proceedings, 2005
ABSTRACTEfficient mid-IR interband cascade (IC) lasers have been developed based on III-V semiconductor materials with lasing emission covering a wavelength range from 2.7 to 5.6 microns. These IC lasers reuse injected electrons in cascade stages for photon generation with high quantum efficiency to achieve high output powers.

Frequency noise characterization of interband cascade lasers

Novel In-Plane Semiconductor Lasers XVIII, 2019
Thanks to their compactness and low-power consumption, Interband Cascade Lasers (ICLs) are emerging sources for mid-infrared (MIR) molecular sensing below 6 mu m. Understanding their noise features is of fundamental importance for applications like high-sensitivity and high-resolution spectroscopy.

Vertically emitting ring interband cascade lasers

Novel In-Plane Semiconductor Lasers XX, 2021
We have demonstrated that both ring quantum cascade (QCLs) and interband cascade lasers (ICLs) are excellent platforms for vertical light emission. Of these two lasers ICLs typically show lower power consumption and lasing threshold, qualifying them especially for miniaturized and battery-powered applications.
