An embodiment of a laser to fiber coupling apparatus having a substrate 110 that supports a laser mount 120, to which is affixed a submount 130 and laser die 140, and an open slot mount 150, in which a light guide 160 is affixed with an adhesive 170, such that the light from the laser 140 is coupled into the light guide 160. The open slot arrangement permits the light guide to be moved in all six translational and rotational degrees of freedom to maximally couple the light from the laser to the light guide. Other embodiments are described and shown.
