This is the simplest of the quantum cascade lasers. An optical waveguide is first fabricated out of the quantum cascade material to form the gain medium. The ends of the crystalline semiconductor device are then cleaved to form two parallel mirrors on either end of the waveguide, thus forming a Fabry–Pérot resonator. The residual ...
A Quantum Cascade Detector (QCD) is a photodetector sensitive to infrared radiation. [2] The absorption of incident light is mediated by intersubband transitions in a semiconductor multiple-quantum-well structure. The term cascade refers to the characteristic path of the electrons inside the material bandstructure, induced by absorption of ...
Quantum dot laser: wide range. Medicine (laser scalpel, optical coherence tomography), display technologies (projection, laser TV), spectroscopy and telecommunications. Quantum well laser: 0.4-20 μm, depending on active region material. Telecommunications: Hybrid silicon laser: Mid-infrared: Low cost silicon integrated optical communications
As such, she works in the fields of optics and semiconductor laser technology. Gmachl has conceived several novel designs for solid-state lasers and her work has led to advances in the development of quantum cascade lasers. [citation needed] QC lasers are a rapidly evolving class of high-performance, mid-infrared, semiconductor light sources.
Laser direct infrared imaging (LDIR) is an infrared microscopy architecture that utilizes a tunable Quantum Cascade Laser (QCL) as the IR source. [1] This new reflectance-based architecture eliminates coherence artifacts typically associated with QCLs.
An interband cascade laser (ICL) is a type of laser diode that can produce coherent radiation over a large part of the mid-infrared region of the electromagnetic spectrum. Separate confinement heterostructure lasers
Interband cascade lasers (ICLs) are a type of laser diode that can produce coherent radiation over a large part of the mid-infrared region of the electromagnetic spectrum. They are fabricated from epitaxially -grown semiconductor heterostructures composed of layers of indium arsenide (InAs), gallium antimonide (GaSb), aluminum antimonide (AlSb ...
The spectroscopy is based on semiconductor quantum cascade laser frequency combs [1] [2] in the mid-infrared wavelength range. The company is based in Zurich, Switzerland and was founded in 2014 and acquired by Sensirion Holding in May 2021. [3]
