Optical module and a method for fabricating a same

摘要

A semiconductor optical amplifier is mounted on a substrate which is provided for a package. Fiber blocks in which plural parallel internal optical fibers are supported are fitted to the package. The optical fibers are optically coupled with the semiconductor optical amplifier via optical waveguides formed on the substrate. V grooves for supporting the optical fibers which protrude out from the fiber block are formed on the substrate. Positionings of the optical fibers are performed by fitting the fiber blocks to the package so that end faces of the optical fibers butt against end walls of the V grooves.
