  • Patent number: 8503843
    Abstract: The present invention provides a hybrid integrated optical module having a high coupling efficiency by suppressing a connection loss between waveguides. A hybrid integrated optical module according to an embodiment of the present invention is an optical module which integrates a semiconductor chip and a PLC chip. The semiconductor chip has a semiconductor waveguide and is mounted on a Si bench. The PLC chip includes a PLC substrate and an optical waveguide formed on the PLC substrate. An end face of the semiconductor chip protrudes from an end face of the Si bench toward the PLC chip side by a protrusion amount X. Gap adjustment (adjustment of a distance D) between the semiconductor waveguide and the optical waveguide becomes possible by setting a position where the end face of the semiconductor chip is brought into contact with an end face of the PLC chip to be a reference position (zero point).

  • Patent number: 8503849
    Abstract: A method of forming a waveguide is disclosed, as well as the waveguide itself. A multilayer stack of light guiding layers is formed, and the multilayer stack is delaminated between light guiding layers to form a waveguide between the light guiding layers. The multilayer stack is delaminated in a patterned region between light guiding layers. Here a new approach is described, wherein hollow microchannels forming a Bragg waveguide assembly are fabricated by controlled formation of thin film delamination buckles within a multilayer stack. A hollow waveguide is formed by alternating layers of the multilayer stack forming light guiding surfaces. The hollow waveguide is formed between layers that delaminate from each other, as for example under applied stress to one or more of the layers. The multi-layer stack may be formed of alternating layers of low and high index of refraction materials, as for example forming omni-directional dielectric reflectors.

  • Patent number: 8503854
    Abstract: In a video playback apparatus that is capable of communicating with a printing device, if an event of which notification is to be given has occurs in the printing device, a situation in which viewing by the user is impeded by the notification and a situation in which unnecessary video is recorded are suppressed. If an error occurs in the printing device, the type of display information prevailing when the error is detected is discriminated (S34). In case of a moving-picture program broadcast, an error message is displayed and the display information starts being stored (S35), thereby making it possible to resume viewing after error recovery. On the hand, in the case of a still picture or other type of display information, an error message is displayed (S310) without storing display information, thereby suppressing unnecessary recording of display information.

  • Patent number: 8503868
    Abstract: An original stream file and an after-recording data file are managed as different files. In the original stream file, data is made up of sets of partial data (CU) divided in accordance with a predetermined interval. Likewise, in the after-recording data file, data is made up of sets of partial data (CA) divided in accordance with a predetermined interval. These sets of data are recorded onto a disc such that the after-recorded data (CA) is recorded in a region adjacent to a relevant original stream (CU). This allows reproduction and real-time after-recording with the use of a general MPEG-2 PS/TS decoder. Moreover, this allows realization of data recording that causes less interruption of reproduction when non-destructive editing is carried out with respect to an after-recorded result.

  • Patent number: 8503882
    Abstract: An optical receiver that can receive WDM signal light in which first and second wavelength bands are combined. Within optical reception units corresponding to each channel is respectively provided tunable dispersion compensator (TDC) modules in which one wavelength band is made a design standard. When known, based on signal light channel information (wavelength, frequency, channel number) notified from outside, that signal light of the second wavelength band is being input to the receiver, then in the TDC module that performed chromatic dispersion compensation of the signal light, control is performed to shift the center frequency of the dispersion compensation range by a predetermined amount corresponding to the wavelength of the signal light. When the signal light of the first wavelength band is input, shift control of the dispersion compensation range is not performed, and the dispersion compensation range at the time of designing is maintained.

  • Patent number: 8503889
    Abstract: A filter-based method of demodulating differentially encoded phase shift keyed (DPSK) optical signals, such as commonly used binary-DPSK (DBDPSK) and quadrature DPSK (DQPSK) signals, that can achieve optimal receiver sensitivity is described. This approach, which combines filtering and differential phase comparison, can reduce the complexity and cost of DPSK receivers by obviating delay-line interferometer-based demodulation. This can improve receiver stability and reduce size, weight, and power, while maintaining the ability to achieve optimal communications performance.

  • Patent number: 8503891
    Abstract: There is a need to provide a multirate burst mode receiver for an OLT to be capable of receiving a high-speed burst signal without the need for a special capability of an ONU in a PON system including a mix of ONUs at different transmission bit rates. A multirate burst mode receiver according to the invention includes a signal input discrimination section and a bit rate discrimination section. The signal input discrimination section detects an average amplitude to discriminate signal input. The bit rate discrimination section detects an envelope curve for a high-frequency component to discriminate a signal bit rate. Based on a discrimination result from the signal input discrimination section and the bit rate discrimination section, the multirate burst mode receiver switches a setting for an optical signal reception section and a serial-parallel converter corresponding to the reception bit rate.
