An optoelectronic assembly includes an optical lens element (OLE) coupled
to a substrate. The substrate includes a transducer, a standing structure
on the transducer, a transducer lens supported by the standing structure
over the transducer, and alignment features. The OLE includes an OLE lens
and co-alignment features that couple with the alignment features on the
optoelectronic assembly. When the substrate is coupled to the OLE, the
transducer lens is aligned with the OLE lens.
