20130077980 | OPTICAL RECEIVER - The invention provides a solution for the full integration of a coherent receiver on Indium Phosphide (InP) or other material that has a number of advantages over current coherent receiver design. PIN waveguides can be reverse biased and forward biased to modify the mode effective index so as to realize an integrated polarization beam splitting function and the 90 degree optical hybrid. The fabrication tolerance is therefore greatly increased; resulting in much reduced complexity and cost for the final receiver. | 03-28-2013 |

20120114003 | LASER DEVICE, A LIGHT SIGNAL GENERATION DEVICE, AND AN OPTICAL RESONATOR AND A METHOD FOR PRODUCING LIGHT - A laser device includes a ridge waveguide having an active layer between upper and lower cladding layers. A ridge formed in the upper cladding layer defines the width of a light guiding region in the active layer, and is formed so that a portion of the light guiding region extends into the ridge. A plurality of reflecting slots extend across and into the ridge to a depth sufficient to extend into the extending portion in order that the reflectivity of each slot is on the order of 2%. The slots intersect more than 20% of the total mode energy in the light guiding region, and this in combination with the gain of the active layer facilitates lasing within the light guiding region independently of the reflectivity of end facets of the waveguide. The laser device is particularly suitable for integrally forming with other optical components on a single semiconductor chip. | 05-10-2012 |
20120293804 | System and Method for Measuring Optical Signal-to-Noise Ratio - The invention provides a system and method for measuring optical signal-to-noise-ratio (OSNR) in an optical communication system. A channel filter is adapted to select one specific optical communication channel from a wavelength-division-multiplexing (WDM) optical communication system, wherein the channel comprises an optical signal carrying digital bit information and noise from associated optical power amplifiers in the system. At least one optical delay interferometer is adapted to measure at least two interferograms of the noisy signal. The invention provides a mechanism for calculating the in-band OSNR from extinctions of the interferograms measured at different optical delays by referring to each other, wherein said optical delays are selected to be substantially less than a bit period of the optical channel. Because of the selection of the optical delays and/or the self-reference between the two measurements, the system can follow any changes happening to the signal such as additional filtering, self (cross)-phase modulation, the bias and drive signal change of the modulator used to generate the optical signal. | 11-22-2012 |

20090045580 | GAME APPARATUS - The game apparatus has a plurality of elongate coloured building blocks. During the course of a game a number of the blocks are built up block by block in a desired orientation on an associated plinth forming an upright structure until this structure collapses. Each building block is of square section and is subdivided into five coloured engagement portions each of which has a different colour. When building up the structure the coloured building blocks may only interengage where their touching engagement portions are of the same colour. | 02-19-2009 |
