Patent attributes
It is provided that an optical functional integrated unit and a method for manufacturing thereof in which a positive optical device and a passive optical device including a silicon waveguide can be readily integrated. An optical functional integrated unit includes a semiconductor optical amplifier, a photonics device, a mounting board, pedestals and. The pedestals and are provided on the mounting board. The semiconductor optical amplifier is mounted on the pedestal and outputs a light from an active layer. The photonics device is mounted on the pedestal. The photonics device includes silicon waveguide to which the light output from the semiconductor optical amplifier is guided.
