Quantum Cascade Lasers (QCLs) are semiconductor lasers that, in contrast to common diode lasers, operate on intersubband transitions in the conduction band of the materials

Many QCL devices tend toward a laser core design consisting of 30-40 stages (about 1-2 μm thick,) with a device length of 2-5 mm and

Quantum mechanical selection rules dictate that laser light generated by a QCL must be polarized along the growth direction of the superlattice in the laser

The Lattice Constant of a semiconductor describes the spacing (in angstroms) of the atoms in the semiconductor crystal of that material. Growing different semiconductor material
