Method of creating a photonic via using deposition

A method of making a photonic via comprising:

• making a hole in a substrate, wherein the hole extends from one side of the substrate through the substrate to an opposite side of the substrate, heating the substrate to expand the hole;
• inserting a fiber optic into the hole;
• cooling the substrate to contract the hole to hold the fiber optic in place;
• polishing the substrate;
• applying a polymer on top of the fiber optic;
• and
• curing the polymer to form a lens.

• and
• forming a waveguide having an angled surface to redirect light in a direction substantially perpendicular to the fiber optic, comprising:
• depositing a cladding layer on the substrate;
• depositing a layer of optical material over the cladding;
• depositing a mask on the optical material with an opening over the hole;
• and
• etching to form at least one angled surface in the optical material.
