Abstract
A method for manufacturing an optoelectronic assembly includes attaching an optical die, a first lens, a second lens, and an optical fiber to a sub-mount. The sub-mount includes a plurality of passive alignment features which aid in the passive alignment of the optical die, the first lens, and the optical fiber for attachment. The second lens is actively aligned between the first lens and the optical fiber, based on a coupling efficiency with which an optical signal emitted by the optical die is coupled into the optical fiber through the first and second lenses. The active alignment of the second lens includes calibration of at least one of a position and a degree of tilt of the second lens.
