= Strained quantum-well laser
{wiki=Strained_quantum-well_laser}
A strained quantum-well laser (SQWL) is a type of semiconductor laser that utilizes quantum wells under strain to enhance performance characteristics. Quantum wells are thin layers of semiconductor material where charge carriers (electrons and holes) are confined in one dimension, leading to quantized energy levels. In a strained quantum-well laser, the quantum wells are created within a lattice structure that is intentionally misaligned or geometrically altered.
