1. A lens-based connector assembly comprising:
a glass-based optical substrate comprising:
at least one optical element within the optical substrate, wherein the at least one optical element comprises an array of fiber holes; and
at least one alignment feature positioned at an edge of the glass-based optical substrate; and
a connector element comprising a recess having an interior surface, the interior surface comprising at least one connector alignment feature, wherein:
the glass-based optical substrate is disposed within the recess such that the at least one alignment feature of the glass-based optical substrate engages the at least one connector alignment feature and the glass-based optical substrate is fixed to the connector element with an adhesive; and
each of the at least one alignment feature and the at least one connector alignment feature comprises a positive alignment feature and a negative alignment feature.
