    摘要: The present invention utilizes a high-speed serial data transceiver to generate two high-speed electric pulse signals. After passing through a gain network, the signals are used for driving an electro-optic phase modulator (PM) so as to realize phase modulation of photon signals. The present invention may directly use a high-speed digital signal to realize a four-phase modulation function needed by the BB84 quantum key distribution protocol without using a digital to analog converter or an analog switch. This can prevent modulation rate from being restricted by links including digital-to-analogue conversion, switching of the analogue and the like. A dual-electrode electro-optic phase modulator scheme can also effectively reduce requirements for amplitude of a modulation driving signal, thus facilitating realization of high-speed phase modulation, which meets requirements of quantum key distribution.

    摘要: An electro-optic device includes a first electrode, a second electrode spaced apart from the first electrode, and an active layer of organic semiconducting material between the first electrode and the second electrode. The active layer includes a quasi-bilayer in which a first plurality molecules from a first layer of active material is interpenetrated by a second plurality of molecules from a second layer of active material formed on the first layer. The first and second pluralities of molecules provide donor-acceptor pairs such that the quasi-bilayer has at least a portion that is a bulk heterojunction active layer. Each of the first plurality of molecules has a long axis that is longer than corresponding transverse axes and the long axis is substantially aligned along a common direction such that the active layer is more sensitive to a first polarization of incident light than a second polarization of the incident light, wherein the first polarization and the second polarization are orthogonal polarization components of the light.

    摘要: A channel decoding method and decoder are disclosed. The decoding method is based on a Circular Viterbi Algorithm (CVA), rules out impossible initial states one by one through iterations according the received soft information sequence, and finally finds the global optimal tail-biting path. In the present invention, all impossible iterations are ruled out through multiple iterations, and only the initial state having most likelihood with the received sequence survives. The algorithm is finally convergent to an optimal tail-biting path to be output. In addition, the method also updates a metric of a maximum likelihood tail-biting path (MLTBP) or rules out impossible initial states through the obtained surviving tail-biting path, thereby effectively solving the problem that the algorithm is not convergent due to a circular trap, providing a practical optimal decoding algorithm for a tail-biting convolutional code, reducing the complexity of an existing decoding scheme, and saving the storage space.
