Abstract: PROBLEM TO BE SOLVED: To improve reliability of an integrated element by providing a masks of an oxide film and a nitride film on the surface of a substrate in the vicinity of many periodicities, adding raw-material gas including chlorine by organic- metal gaseous-phase growing method, and forming the quantum well structure having the different periodicities on the same substrate by one selective growth. SOLUTION: On an n-InP substrate 1 or an n-InP buffer layer 2, a selective- growing SiO2 mask 3 is deposited. An active layer 4, which is constituted of an n-InGaAsP guide layer 7, a barrier layer 8, a well layer 9, a CH3 Cl added well layer 10 and undoped guide layer 11, is selectively grown by an organic- metal gaseous-phase growing method. Then, the selective-growing SiO2 mask 3 is removed, p-InP clad layers 12 and 13 and a p-InGaAs cap layer 14 are sequentially grown. A p-type cap layer 15 and an n-type cap layer 16 are evaporated. Cleavage is performed at a laser part and a beam expanding part, and the element is formed. Thus, the periodicities of the beam expanding part and the laser part can be independently controlled, and the emitting angle can be decreased.
