Abstract
Technologies for coupling to and from a photonic integrated circuit (PIC) with an optical isolator are disclosed. In one embodiment, light beams from waveguides on a PIC die are reflected towards flat mirrors on the bottom surface of the PIC die. The flat mirrors reflect the light towards curved mirrors defined in a top surface of the PIC die, which collimate the beam and direct the collimated beams out the bottom surface of the PIC die. An optical isolator below the PIC die can allow the beams to pass while blocking beams in the opposite direction.
