英文摘要	PURPOSE: To performing efficiency carrier injection and to achieve customization for a wide range of the wavelength by providing a quantum well of a semiconductor with a specific relationship for the band energy of a semiconductor layer. CONSTITUTION: A device is composed of first and second regions 14 and 16, made of a semiconductor material having conduction and valence electron allowed energy bands that are separated by the band gap of energy and are formed by a corresponding band edge and a quantum-well region 12 that is held between them. The quantum-well active region 12 has two energy states E1 and E2 under a bias voltage. The first energy state E1 exists in one of the band gap from the first and second regions 14 and 16, and at the same time is formed by a semiconductor material that exists in one of the other allowed energy band, thus achieving an efficient carrier injection and customization for a wide range of wavelengths.
