摘要： PURPOSE:To provide an optical integrated circuit capable of having high yield and greatly reducing cost by assembling a photodetector with high precision. CONSTITUTION:A semiconductor laser 4 mounted on a submount 3 and the multi-divided photodetector 5 are assembled on a 1st transparent substrate 1. A mirror 8, a hologram beam splitter 6, a hologram collimator lens 9, and an aspherical objective lens 7 are formed integrally on the top and reverse surfaces of a 2nd transparent substrate 2. Then the 1st transparent substrate 1 is supported by an alignment adjusting means so that they can move relatively in both axial directions X and Y and rotate relatively arround a Z axis as a center to the 2nd transparent substrate 2 while holding an adhesive 10 therebetween. The light emitted the semiconductor laser 4 and reflected by an optical disk as return light is detected by the multi-divided photodetector 5 and the 1st transparent substrate 1 is aligned about the 2nd transparent substrate 2 so as to obtain a tracking servo signal and a focus servo signal; and then the adhesive 10 is cured to fix the substrates 1 and 2.

摘要： PURPOSE:To manufacture the title semiconductor laser element having excellent optical and electrical characteristics by a method wherein a clad layer and an active layer having flat interface and excellent optical crystallizability as well as capable of facilitating the control of thickness and mixed crystal ratio of the active layer are grown. CONSTITUTION:The first lower n-AlxGa1-xAs clad layer 121 is grown above an n-GaAs substrate 10 at a relatively high substrate temperature. Next, an n-GaAs thin layer 13 is grown while lowering the substrate temperature. Next, the first upper n-AlxGa1-xAs clad layer 122, an AlyGa1-yAs active layer 14 and the second lower p-AlxGa1-xAs clad layer 161 are grown at a relatively low substrate temperature. Next, a p-GaAs thin layer 15 is grown while raising the substrate temperature. Finally, the second p-AlxGa1-xAs upper clad layer 162 is grown at a relatively high substrate temperature.

摘要： PURPOSE:To prevent unstable operation from occurring where laser light intensity distribution is shifted horizontally even if the number of carries which are injected into an activation layer increases by providing a stripe-shaped part with a higher refractive index in the center of a stripe-shaped refractive index type waveguide path. CONSTITUTION:An n-Al0.33Ga0.67As first clad layer 2, a p-Al0.03Ga0.92As activation layer 3, and a p-Al0.33Ga0.67As second clad layer 4 are laminated on an n-GaAs substrate 1. A stripe-shaped first ridge 10 is formed at the second clad layer 4 and a stripe-shaped second ridge 11 is formed in the center of the first ridge 10. n-GaAs light absorption layers 6 with a smaller energy gap than the activation layer 3 is formed at both sides of the first ridge 10 on the second clad layer 4. An Al0.42Ga0.58As third clad layer 5 is formed on the light absorption layer 6 and on the first ridge 10 of the second clad layer 4. The third clad layer 5 has a smaller refractive index than that of the second clad layer 4.
