Latest Patents

Aratake is credited with 1 patent: “Optical module.” The invention describes a package containing a multi-chip integrated device with an optical functional element connected at both ends to planar lightwave circuits (PLCs). Folded waveguides in the PLCs connect the optical element’s waveguides to optical fibers. A connecting part links each PLC to the fibers, allowing the fibers to exit from opposing package surfaces while connecting to the optical functional element on the same face. The design addresses the challenge of making an optical module smaller without compromising its fiber connections.
