Abstract
Various embodiments provide methods for fabricating a couplable electro-optical device. An example method comprises fabricating a pillar on a substrate by forming a lens spacer portion about an electro-optical component fabricated on the substrate; and adhering unshaped lens material to an exposed surface of the pillar. The exposed surface of the pillar is disposed opposite the substrate. The example method further comprises maintaining the unshaped lens material at a reflow temperature for a reflow time to allow the lens material to reflow into a formed lens shape, and curing the lens material to form an integrated lens having the formed lens shape secured to the lens spacer portion and formed about the electro-optical component on the substrate.
