We review the recent development of high-performance short-wavelength (λ ~ 3.05-3.8 μm) strain-compensated InGaAs/AlAs(Sb)/InP quantum cascade lasers (QCLs). The lasers are demonstrated in which wavelengths as low as 3.05 μm are obtained at temperatures up to 295 K. We also verify that...
In this work, the tunability properties of short-wavelength (λ ~ 3.9 μm) quantum-cascade lasers (QCLs) were studied, which is a first in the world at suc... I. Bayrakli,M. Wienold,M. Hempel,... - 《Optical\s&\squantum Electronics》 被引量: 6发表: 2009年 MBE growth of strai...

light sources were either limited to mid-infrared wavelengths emitted by epitaxially grown quantum cascade lasers14or relied on external light sources such as vertical-cavity surface-emitting lasers (VCSELs) that emit at near-infrared wavelengths and that are flip-chip mounted to the underlying Si3N...
The recent availability of novel pulsed and CW quantum cascade distributed feedback (QC-DFB) lasers as mid-infrared spectroscopic sources address this need [19] but such techniques requires the precise knowledge of the high resolution spectra of formaldehyde. For the three fundamental bands, ν4 (...
