Latest Patents

Among Jinguji's latest innovations are the optical multiplexer and optical demultiplexer. These inventions are designed to provide transmission characteristics that remain unaffected by fabrication errors, while also ensuring small group delay dispersion. In his optical demultiplexer, a cross output port of a second demultiplexer element is selected alongside a through output port of a third demultiplexer. Remarkably, the first demultiplexer maintains a passband equal to the second's cross output, while the third's through output corresponds with the first demultiplexer's cross output. Additionally, the configuration allows for opposite group delay characteristics, improving the overall efficiency of optical signal processing.

Furthermore, Jinguji has also developed an optical multi/demultiplexer featuring a wide passband and reduced crosstalk among channels. This innovative device incorporates arrayed waveguide gratings and a 2×2 optical signal processor, augmented by phase shifters that correct fabrication-related phase errors. Such features allow Jinguji's multiplexer to widen the extinction bandwidth, further advancing optical communication technologies.
