Claim:
1. A method of aligning components in a multichannel optical or optoelectronic transmitter, the method comprising: a) passively fixing a plurality of light emitters in place on a substrate; b) passively fixing one or more optical subassemblies in predetermined locations on the substrate by a process comprising applying an adhesive to the one or more subassemblies and/or the substrate and contacting the one or more subassemblies to the substrate, wherein each optical subassembly (i) receives light from at least two of the plurality of light emitters, and (ii) comprises a plurality of passive optical components; c) passively fixing one or more additional passive optical components in predetermined locations on the substrate; d) adjusting a position and/or angle of a first one of the one or more optical subassemblies and any additional passive optical components through which light passes from a first one of the plurality of light emitters until a far field spot of the light from the first one of the plurality of light emitters is at or near an end of the optical signal transmission medium; e) adjusting positions of any remaining ones of the one or more optical subassemblies and the one or more additional passive optical components to align the light from the remaining one(s) of the plurality of light emitters with the far field spot; and f) after adjusting the positions of the one or more optical subassemblies, curing the adhesive.
