  • Optical waveguide type synaptic weight modulator with nematic liquid crystal cladding
    Patent number: 5388169
    Abstract: 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.
