Japan, Feb. 27 -- NIHON LUMENTUM CO LTD has got intellectual property rights for 'SEMICONDUCTOR OPTICAL DEVICE AND MANUFACTURING METHOD OF THE SAME.' Other related details are as follows:
Application Number: JP,2021-187200
Category (FI): H10H20/812,H01L33/06,H01S5/34
Stage: PROBLEM TO BE SOLVED: To provide a semiconductor optical device excellent in mass productivity.SOLUTION: A semiconductor optical device is provided, comprising: a substrate of a first conductive type; an optical confinement layer of the first conductive type which is arranged above the substrate of the first conductive type; a multi quantum well layer which is constructed by a plurality of well layers and barrier layers arranged above the optical confinement layer of the first conductive type; an optical confinement layer of a second conductive type that is arranged on the multi quantum well layer; and a PL stabilization layer that is arranged between the optical confinement layer of the first conductive type and the multi quantum well layer. The thickness of the PL stabilization layer is the half or more of the thickness of the multi quantum well layer, and a composition wavelength of the PL stabilization layer is shorter than the composition wavelength of the well layer of the multi quantum well layer, and is longer than the composition wavelength of the optical confinement layer of the first conductive type.SELECTED DRAWING: Figure 2 (Grant)
