  • Patent number: 8666204
    Abstract: An optical transmission module includes a semiconductor substrate, a first film layer, an electronic component layer and a waveguide structure. The electronic component layer is used for converting a first electrical signal into an optical signal. The waveguide structure is formed on the first film layer, and includes a first reflective surface, a waveguide body and a second reflective surface. After the optical signal is transmitted through the semiconductor substrate and the first film layer and enters the waveguide structure, the optical signal is reflected by the first reflective surface, transmitted within the waveguide body and reflected by the second reflective surface. After the optical signal reflected by the second reflective surface is transmitted through the first film layer and the semiconductor substrate and received by the electronic component layer, the optical signal is converted into a second electrical signal by the electronic component layer.

  • Patent number: 8644654
    Abstract: The optical coupler module for converting and transmitting electrical/optical signals includes a semiconductor substrate, a first film, a second film, an electrical transmission unit, at least one signal conversion unit and an optical waveguide structure. The first film and the second film are formed on opposite surfaces of the semiconductor substrate. The signal conversion unit and the optical waveguide structure are disposed on opposite sides of the semiconductor substrate. The optical waveguide structure has a reflector and a waveguide body. The optical signal generated from the signal conversion unit sequentially passes the first film, the semiconductor substrate and the second film and enters the optical waveguide structure. Then, the optical signal is reflected by the reflector and transmitted in the waveguide body to be outputted. Alternatively, the optical signal is transmitted in a reverse direction from the optical waveguide structure to the signal conversion unit.

  • Publication number: 20110049554
    Abstract: A package base structure for packaging a light-emitting element and a related manufacturing process are provided. The package base structure includes a semiconductor substrate having a top surface, a receiving space in the top surface and defined by slant surfaces, and a micro diffractive optical element on one of the slant surfaces. To produce the package base structure, a first etching mask with a first etching window is formed on the top surface. The etching window has a sidewall oriented at a bias angle with respect to a specific equivalent crystallographic orientation of the semiconductor substrate. Then, a selective anisotropic etching procedure is performed through the first etching window to form the slant surfaces on the semiconductor substrate. Afterwards, the micro diffractive optical element is formed on the slant surface for collimating or focusing a light beam emitted from the light-emitting element.

    Abstract: An optical pickup head includes a first light source, a second light source, a base, a light adjusting unit, and a light guiding unit. The first light source emits a first wavelength light beam to read a first data density optical storage medium. The second light source emits a second wavelength light beam to read a second data density optical storage medium. The base includes at least a slant surface for reflecting the first wavelength light beam and the second wavelength light beam, so that the first wavelength light beam and the second wavelength light beam are parallel with each other. The light adjusting unit adjusts the first wavelength light beam and the second wavelength light beam to the same optical axis.
