Latest Patents
Sasaki's latest patents include an optoelectronic hybrid integrated module and a light input/output apparatus. The optoelectronic hybrid integrated module features a transparent plate with a light extracting part that outputs light to the outside. It includes an electrode for wiring and an electromagnetic shield. An optical device is flip-chip mounted beneath the light extracting part, while a driver IC is also flip-chip mounted at a specific position. This configuration allows for the emission of optical signals when currents flow from the driver IC, based on external electric logical signals. The light extracting part may incorporate a light coupling material or an optical axis converter.
His second patent describes an optical module with a self-aligned optical element. This module has an optical wave-guide structure formed on a silicon substrate, with a laser diode array solder bonded to first pads on the substrate. The self-alignment is achieved through the surface tension of solder during the reflow stage. The design of the first pads enhances the solder bump's surface tension, ensuring effective bonding without compromising the solder bump's volume.
