Abstract: The present disclosure is generally directed to a TO can laser package that includes an off-center focus lens integrated into a lens cap to compensate displacement of an associated laser diode. The TO can laser package includes a TO header with a mounting structure for directly electrically coupling an associated laser diode to electrical leads/pins without the use of an intermediate interconnect. The mounting structure displaces the laser diode such that an emission surface, and more particularly, an origin thereof, is displaced/offset relative to a center of the TO header. The integrated lens cap includes a focus lens with an optical center that is offset from a center of the TO header at a distance that is substantially equal to the displacement of the laser diode. Thus, the displacement of the laser diode is compensated for by the off-center focus lens to minimize or otherwise reduce optical misalignment.
