In quantum cascade structures, electrons undergo intersubband transitions and photons are emitted. The electrons tunnel to the next period of the structure and the process repeats. Additionally, in semiconductor laser diodes, electrons and holes are annihilated after recombining across the band gap and can play no further part in photon generation.
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
Bell Labs [b] is an American industrial research and development (R&D) company, currently operating as a subsidiary of Finnish technology company Nokia.With a long history, Bell Labs is credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages ...

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.
How much does Halo laser cost? The cost is the biggest downside to Halo IMO. A single treatment will set you back anywhere from $1500 to $2000 depending on where you live, ...
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 ...
