    IPC: G02B6/12

    Abstract: A carrier laser device assembly is provided in which a visible region of a laser that includes an output portion and/or output portion of a waveguide of the laser is visible to an imaging system when the laser is attached to a carrier. The laser may be burned-in and/or tested prior to attachment to a photonic integrated circuit. The output portion and/or output portion of waveguide may be aligned with a corresponding input portion and/or input portion of a waveguide of the PIC as the laser assembly is being attached to the PIC via imaging of the visible portion by the imaging system.
