  • Semiconductor laser device, optical pickup device and semiconductor device
    Patent number: 8471289
    Abstract: A semiconductor laser device includes a Si(100) substrate in which a recess having an opening and a bottom face surrounded by inner wall surfaces is formed, a semiconductor laser element placed on the bottom face, and a translucent sealing glass, mounted on top of the Si(100) substrate, which seals the opening. The laser light emitted from the semiconductor laser element is reflected by a metallic reflective film formed on the inner wall surface and then transmits through the sealing glass so as to be emitted externally.
    Type: Grant
