DUAL-WAVELENGTH SEMICONDUCTOR LASER DEVICE AND METHOD FOR FABRICATING THE SAME |
摘要 |
In a dual-wavelength semiconductor laser in which a first semiconductor laser element and a second semiconductor laser element are integrated onto a substrate made of a compound semiconductor, a constituent material of an etching stopper of the first semiconductor laser element is a material which allows diffusion of impurities less easily than a constituent material of an etching stopper of the second semiconductor laser element.
