Quantum wells are the foundation for semiconductor optoelectronics integrated circuits as well as the key part of optoelectronic devices. Based on the state density,quantum size effects and population inversion in quantum structures we discuss the principles of operation, structure and performance of quantum well lasers. These structures have played a very important role in visible and high-power laser diodes, showing many outstanding properties.
