Abstract:
1. An optical module in which a plurality of packages storing therein optical elements is directly joined to an end face of a waveguide of a planar lightwave circuit, the planar lightwave circuit being positioned on a top surface of a substrate and the end face being positioned at a perimeter sidewall of the substrate so that the waveguide is optically coupled to the optical elements, comprising: a housing storing therein the planar lightwave circuit and the plurality of packages, wherein a bottom surface of the substrate is fixed to an upper face of a protrusion formed in a bottom section of the housing, wherein each of the plurality of packages does not contact the housing, and wherein a plurality of lead pins are attached to each package, each lead pin being electrically coupled to a separate one of the optical elements, the lead pins being fixedly attached to a flexible printed circuit that is fixedly attached to an electric part fixed in the housing such that the optical elements are electrically coupled to the electric part via the flexible printed circuit.
