Abstract: Method and apparatus for vision assisted optical alignment. In the apparatus, one or more main waveguides of a photonic integrated circuit (PIC) are selected, and respective one or more corresponding auxiliary waveguides are terminated with a respective scattering structure. The scattering structures deflect externally supplied light out of the PIC for detection by a camera or photo detector to provide feedback on the amount of light coupled into the main waveguides during the optical alignment process. The method and apparatus eliminate the need to power up the PIC circuitry, speed up the subsequent alignment process, and allow control and failure analysis of multiple channels at once.
