Abstract
The present invention provides an optical module in which an optical alignment between the light-emitting device and the waveguide device may be simplified. The optical module of the present invention has a waveguide device, first and second lenses, a housing and an optical sub-assembly (OSA) unit. Two lenses optically couple with respective end faces of the waveguide device. The housing encloses the waveguide device, and first and second lenses therein. The OSA unit has a package and a light-emitting device installed in the package. In the present invention, the OSA unit is aligned with the housing such that the light-emitting device is optically coupled with the waveguide device via the first lens.
