At least two independent realizations of the reservoir are generated from at least two Gaussian white noises. At least one region is defined within the reservoir and a parameter allowing the shape and the size of this region to be modified is defined. A new realization of the reservoir is then generated from a linear combination of the white noises. The coefficients of this linear combination depend on the parameter allowing the region to be modified. A local objective function measuring, within this region, a difference between dynamic data simulated from the new realization and the measured dynamic data is then calculated. Finally, the image of the reservoir is constructed by iteratively modifying the parameter so as to minimize the local objective function. | 01-13-2011 |

20090003396 | INTEGRATED PHOTONIC SEMICONDUCTOR DEVICES HAVING RIDGE STRUCTURES THAT ARE GROWN RATHER THAN ETCHED, AND METHODS FOR MAKING SAME - A SAG technique is used to grow the ridge structure in a photonic semiconductor device, such as an electroabsorption modulator integrated with a distributed feedback laser (EML) assembly. The adoption of this SAG technique to grow the ridge structure results in the formation of a self-assembled and self-aligned ridge structure that has a very precise configuration. The use of this process enables straight, bent and tilted ridge structures to be formed with high precision. In addition, because the ridge structure is self-assembled and self-aligned, a lesser number of processing steps are required to create the photonic device in comparison to the known approach that uses wet chemical etching techniques to form the ridge structure. The high precision of the ridge structure and the lesser number of processing steps needed to create the device increase manufacturing yield and allow overall cost of the device to be reduced. | 01-01-2009 |

20120183007 | SURFACE-EMITTING SEMICONDUCTOR LASER DEVICE IN WHICH AN EDGE-EMITTING LASER IS INTEGRATED WITH A DIFFRACTIVE OR REFRACTIVE LENS ON THE SEMICONDUCTOR LASER DEVICE - A surface-emitting semiconductor laser device is provided that includes an edge-emitting laser formed in various layers of semiconductor material disposed on a semiconductor substrate, a polymer material disposed on the substrate laterally adjacent the layers in which the edge-emitting laser is formed, a diffractive or refractive lens formed in or on an upper surface of the polymer material, a side reflector formed on an angled side reflector facet of the polymer material generally facing an exit end facet of the laser, and a lower reflector disposed on the substrate beneath the polymer material. Laser light passes out of the exit end facet and propagates through the polymer material before being reflected by the side reflector toward the lower reflector. The laser light is then re-reflected by the lower reflector towards the lens, which directs the laser light out the device in a direction that is generally normal to the upper surface of the substrate. | 07-19-2012 |

20120281727 | SURFACE-EMITTING SEMICONDUCTOR LASER DEVICE IN WHICH AN EDGE-EMITTING LASER IS INTEGRATED WITH A DIFFRACTIVE LENS, AND A METHOD FOR MAKING THE DEVICE - A surface-emitting semiconductor laser device is provided that includes an edge-emitting laser integrated in a semiconductor material with various reflectors and a diffractive lens. The edge-emitting laser has a first section comprising an active MQW region, a second section comprising a passive region and a third section comprising a semi-insulating or un-doped semiconductor bulk layer. This configuration ensures that the injection current will pass through all of the layers of the active region, thereby preventing the occurrence of optical losses due to un-injected areas of the MQW active region. In addition, the inclusion of the passive region ensures that there is no current passing through the interface between the active MQW region and the regrown semiconductor bulk layer. The latter feature improves performance and device reliability. | 11-08-2012 |

20150112985 | System and Method for Querying Disparate Data Sources in Real Time - A system and method for querying disparate data sources in real time utilizes a plurality of listeners and at least one data adapter operated on a request proxy. A interface specific data query is received from a client account by the request proxy through a specific listener. The interface specific data query is formatted into an agnostic request object that is then forwarded to a specific adapter, wherein a specific method is determined from a plurality of methods for the specific adapter. The request proxy retrieves requested data from at least one data source through the specific adapter. The requested data is then formatted into an agnostic response object that can be cached on the request proxy. The agnostic response object is then formatted into a interface specific response stream by the request proxy and the interface specific response stream is sent to the client account through the specific listener. | 04-23-2015 |
