Mid-infrared type-II interband cascade lasers

IEEE Journal of Quantum Electronics, 2000
We describe the progress made in the development of type-II interband cascade lasers emitting in the midinfrared (3.8–3.9 μm) spectral region. Three nominally similar molecular beam epitaxy growths on substrates from different vendors show qualitatively different electrical and optical properties.

Interband cascade laser progress

SPIE Proceedings, 2008
Recent advances in the development of mid-IR antimonide type-II "W" interband cascade lasers have led to a considerably improved high-temperature operation of the devices. We report an experimental investigation of four interband cascade lasers with wavelengths spanning the mid-infrared spectral range, i.e., 2.9-5.2 μm near room temperature in ...

Interband cascade lasers with long lifetimes

Applied Optics, 2015
Narrow-ridge interband cascade lasers were subjected to accelerated aging. The aging curves were statistically evaluated by a log-normal distribution of the failure time, and by the mixed effects of the degradation parameters. Based on 10,000 h of output power trend data for lasers operating at 90°C and the maximum cw power, an unexpectedly long ...

Ring Interband Cascade Lasers

Conference on Lasers and Electro-Optics, 2018
We present ring-shaped interband cascade lasers with light emission through the GaSb substrate. Measurements of the projected nearfields revealed a radial polarization, owing to the nature of the optical interband transitions.

Low threshold interband cascade lasers

SPIE Proceedings, 2013
Various semiconductor laser concepts have been researched during recent years to cover the mid-infrared (MIR) spectral range with robust, compact and reliable coherent sources operating at ambient temperatures. Among them, interband cascade lasers [1] (ICLs), which unite interband transitions with the concept of cascading active regions, have ...

Interband Cascade and Quantum Cascade Ring Lasers

Conference on Lasers and Electro-Optics, 2020
Quantum cascade and interband cascade lasers are fabricated into surface and substrate emitting coherent light sources and detectors. We report about latest achievements in terms of power, temperature and dynamic performance of on-chip sensing systems.

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.
