A quantum well is a thin layer which can confine (quasi-) particles (typically electrons or holes) in the dimension perpendicular to the layer surface, whereas the movement in the other dimensions is not restricted. Semiconductor quantum wells are often used in the active regions of laser diodes, where they are sandwiched between two wider layers with a higher bandgap energy. These cladding layers function as a waveguide, while electrons and holes are efficiently captured by the quantum well, if the difference in bandgap energies is sufficiently large.
