Terahertz Quantum Cascade Lasers
SPIE Proceedings, 2003Unipolar semiconductor injection lasers emitting at THz frequencies (from 4.3 THz down to 2.8 THz) are discussed. The devices are based on interminiband transitions in chirped GaAs/AlGaAs superlattices that are arranged in a quantum-cascade scheme. The core, featuring about 100 repetitions of this type of superlattice, is embedded into a novel kind of ...

Science, 1994
A semiconductor injection laser that differs in a fundamental way from diode lasers has been demonstrated. It is built out of quantum semiconductor structures that were grown by molecular beam epitaxy and designed by band structure engineering. Electrons streaming down a potential staircase sequentially emit photons at the steps.

The recently demonstrated quantum cascade laser is a fundamentally new semiconductor laser.1-3 It relies on only one type of carrier (unipolar laser) and on quantum jumps of electrons between discrete conduction band energy levels of quantum wells. As such the wavelength can be tailored over a very wide range from the mid-ir (a few microns) to the far ...

Quantum Cascade Lasers (QCLs) represent a significant advancement in laser technology, enabling a broad range of applications due to their unique operational principles. Unlike traditional semiconductor lasers that rely on inter-band transitions, QCLs use intersubband transitions within quantum wells, allowing for emission in the mid-infrared and ...

As a result of mass production, millions of semiconductor diode lasers are manufactured each month and appear in products ranging from telecommunications transmitters to DVD players and laser pointers. For traditional laser diodes, the applications are often dictated by what part of the electromagnetic spectrum is accessible.
