Abstract
A method of fabricating an optical module includes attaching a lens to a platform of the optical module such that the lens remains in precise alignment with a light source (e.g., a laser diode) and a target optical fiber even after the lens is attached or fixed to the platform. The optical module includes a micro-lens assembly, comprising a bridge and a micro-lens holder holding a micro-lens. The micro-lens holder is initially to the light source to substantially optimize coupling of light into the input aperture of the optical fiber. Next, the bridge is inserted beneath the micro-lens holder on the platform. Subsequently, the bridge is fixedly attached to the platform. The micro-lens holder is realigned to the light source to substantially optimize coupling of light into the input aperture of the optical fiber and then the micro-lens holder is fixedly attached to the bridge.
