  • Patent number: 8290325
    Abstract: Embodiments of the present invention describe a waveguide-based photodetector device and its methods of fabrication. The waveguide photodetector device comprises a substrate having a cladding structure formed thereon. A waveguide element for receiving optical signals is disposed within the cladding structure. A portion of the waveguide element is encapsulated by a photodetector element that detects the optical signal received by the waveguide element and generates an electrical signal based on the optical signal. Encapsulating the waveguide element in the photodetector element improves coupling efficiency and enables a waveguide photodetector device with higher speeds and higher responsivity.

  • Patent number: 8277131
    Abstract: A semiconductor optical communication module includes a semiconductor chip mounted on a chip carrier and a lens assembly having an end parallel to and facing the front edge of the chip carrier. The semiconductor chip has a front facet oriented at an acute angle to the front edge of the chip carrier. An optical waveguide in the semiconductor chip transmits an optical signal that propagates on an optical axis extending from the front facet of the semiconductor chip to the end of the lens assembly. The optical axis is orthogonal to the end of the lens assembly and the front edge of the chip carrier. The angled mounting of the semiconductor chip on the chip carrier allows the lens assembly to be placed close to the edge of the chip carrier, and to be moved for optical axis adjustment without striking the chip carrier.

  • Patent number: 8277039
    Abstract: An inkjet printer prevents the paper from lifting away from the platen when the suction action of the platen is stopped, and thereby prevents paper jams and other printing problems. The printer 1 conveys the printing paper 12a while holding the paper 12a to the surface of the platen 19 by a suction mechanism 50. After the automatic paper cutting operation is completed, the leading end part 12b of the printing paper 12a is retracted from the cutting position B to the printing start position A on the platen 19, and the printer 1 waits for the next print job with the printing paper 12a held against the platen 19. When a power conservation mode or power off mode is entered, the control unit 61 of the printer 1 advances the leading end part 12b of the printing paper 12a from the printing start position A to the cutting position B so that the paper is held by the downstream-side paper feed roller 34 and pressure roller 35, and then stops the power supply to the suction mechanism 50 of the platen 19.

  • Patent number: 8270787
    Abstract: An optical fiber coupler is formed of a section of optical fiber that is positioned between a conventional input fiber (for example, a single mode fiber) or waveguide and a coiled optical fiber device. The adiabatic coupler is coiled (or, at least, curved) to assist in transforming a conventional fundamental mode optical signal propagating along the longitudinal axis of the input fiber to an optical signal that is shifted into a peripheral region of the coiled optical fiber. Moreover, the pitch of an inventive coiled optical fiber coupler can be controlled to assist in the adiabatic transformation process.
