    • The present invention relates to an optical waveguide type synaptic weight modulator with a nematic liquid crystal cladding layer. The modulator can be used for optronics and optical neural computing. The modulator includes a multichannel waveguide provided on a glass substrate, electrodes which are provided on the glass substrate and which sandwich the channels of the waveguide, a nematic liquid crystal cladding layer provided perpendicularly to the waveguide and electrodes, a control power supply connected to the electrodes, a light source prism coupled to the waveguide, and a multimode fiber end surface coupling an output of the waveguide to a photomultiplier. The nematic liquid crystal cladding layer provides an electrooptical effect and is fixed by an orientation film. Weights are added to each signal in the same manner as the synaptic action of a neural circuit by controlling the power distribution of an input signal consisting of a combination of different waveguide modes by an electric deflection effect with respect to a liquid crystal molecular direction.
    • 本发明涉及具有向列型液晶包层的光波导型突触重量调制器。 调制器可用于光电和光学神经计算。 调制器包括设置在玻璃基板上的多通道波导,设置在玻璃基板上并夹着波导通道的电极,垂直于波导和电极设置的向列型液晶包层,连接到波导的电极 电极,耦合到波导的光源棱镜,以及将波导的输出耦合到光电倍增管的多模光纤端面。 向列液晶包层提供电光效果,并通过取向膜固定。 通过相对于液晶分子方向的电偏转效应控制由不同波导模式的组合组成的输入信号的功率分布,以与神经电路的突触动作相同的方式将权重添加到每个信号。
