Abstract
Technologies for beam expansion for vertically-emitting photonic integrated circuits are disclosed. In the illustrative embodiment, waveguides in a photonic integrated circuit (PIC) die guide light to vertical couplers, which direct the light from the waveguides out of the top surface of the PIC die. A glass microoptic substrate is mounted on the top surface of the PIC die, positioned over the vertical couplers. A mirror in the glass microoptic substrate reflects the light from the vertical couplers to propagate in a direction parallel to the top surface of the PIC die. Another set of mirrors in the glass microoptic substrate focus the light from each waveguide into a collimated beam directed out of the top surface of the glass microoptic substrate.
