Latest Patents
Kuwahara holds a patent for an optical module, which includes a transmitter, receiver, optical switch, and optical communication unit. The patent also covers an add-and-drop multiplexing unit and a method for manufacturing the optical module. This method focuses on aligning the height of a polymer waveguide to the height of a core layer of a semiconductor element. The optical module is designed to mount the semiconductor element on its polymer waveguide substrate. The process involves forming a waveguide on a silicon substrate coated with an oxide film using a polymer with a higher refractive index than the oxide film. The waveguide consists of a lower cladding layer, a core layer, and an upper cladding layer. Notably, the lower cladding layer is thinner than conventional designs, and the core layer height is set between 5 to 10 micrometers. This innovative approach allows for the fabrication of optical modules with fewer process steps and at a lower cost compared to traditional methods.
