20130236137 | OPTICAL PULSE DELAY GENERATOR - An optical pulse delay generator is provided. The optical pulse delay generator includes a first optical converter which is dispersive and separates the spectral components of the incoming optical pulse in a time domain. The first optical converter generating a converted optical signal. The optical pulse delay generator also includes a modulator to modulate the converted optical signal and to generate a modulated optical signal and a second optical converter connected to the modulator. The second optical converter being dispersive for overlaying the previously separated spectral components in the time domain and generating the delayed optical output pulse. The dispersion imposed by the second optical converter has the same amount of dispersion, but the opposite sign, as the first optical converter. At least one of the first and second optical converter includes at least two waveguide resonator rings which differ in their optical length. | 09-12-2013 |

At least one nanostructure is placed on top of the second layer in an area, which is located above the at least one unmodified section of the first layer or adjacent thereto, said at least one nanostructure being formed by a strain-sensitive third material deposited on the locally strained second layer. | 04-25-2013 |
20120295319 | Method of Modifying a Yeast Cell for the Production of Ethanol - The invention relates to a method of modifying a yeast cell for the production of ethanol. According to the invention, the activity of the Gpd1 protein and/or the Gpd2 protein is reduced. | 11-22-2012 |
20100080068 | MEMORY CELL, AND METHOD FOR STORING DATA - The invention relates, among other things, to a memory cell for storing at least one piece of bit data. Said memory cell comprises at least two electrical terminals and a semiconductor structure with a band curve (EL) that has at least one potential well. The charged state of the potential well with charge carries can be increased by applying a supply voltage (Us=Uspeis) to the two terminals, can be reduced by applying a discharge voltage (Us=Usperr), and can be maintained by applying a maintaining voltage (Us=Ubei), the respective charged state of the potential well defining the piece of bit data of the memory cell. According to the invention, the semiconductor structure has a space charge region (Wn) while the potential well is formed by a semiconductor heterostructure. The semiconductor heterostructure and the space charge region are spatially arranged relative to one another in such a way that the semiconductor heterostructure is located within the space charge region when the maintaining voltage is applied, at the edge of or outside the space charge region when the supply voltage is applied, and within the space charge region when the discharge voltage is applied. | 04-01-2010 |
20100074293 | Single-Photon Source and Method for the Production and Operation Thereof - In a method for the production of a single photon source with a given operational performance, the given operational performance for the individual photon source may be fixed by a directed setting of the fine structure gap of the excitonic energy level for at least one quantum dot. The at least one quantum dot is produced with a quantum dot size corresponding to the fine structure gap for setting. | 03-25-2010 |

20080232803 | Hybrid Optical Network and a Method of Routing Data Packets in a Hybrid Optical Network - A hybrid optical network comprising a single channel optical ring network with a plurality of ring nodes and a star subnetwork. The star subnetwork comprises a central wavelength router, a plurality of combiners being connected to input ports of the central wavelength router, and a subset of the ring nodes of the ring network, each node of the subset including a tunable transmitter and a tunable receiver to communicate optical data packets over the star subnetwork. Optical data packets routed between two ring nodes of the subset over the star subnetwork are assigned a specific wavelength that determines the routing of the data packets through the central wavelength router. The invention further regards a method of routing data packets between a source ring node and a destination ring node of a hybrid optical network. | 09-25-2008 |
