ABSTRACT:
In an optical module with a substrate having an optical unit mounted thereon which substrate is provided on the bottom of a package so that the optical unit is optically coupled with an end of an optical fiber extending into the package, a chip carrier, including the optical unit, is die-bonded to a conductive land formed on the substrate. A recess is formed in the bottom of the package which faces the land. Thus, a capacitance of a parallel-plate capacitor formed by the land and the bottom of the is made negligibly small.
