Photonic glass layer substrate with embedded optical structures for communicating with an electro optical integrated circuit

A device, comprising:

• a layer comprising:
• a first waveguide of a plurality of waveguides disposed therein having a first end and a second end;
• a reflective lens disposed in the layer and adjacent to the first end of the first waveguide;
• and
• one or more vias extending to a bottom surface of the layer and configured to be electrically connected to a package substrate;
• a fiber connector comprising an optical fiber aligned with the reflective lens and disposed over a fiber region of the layer at a first end of the layer;
