Abstract
A method is for aligning an electro-optic device. The method may include initially positioning an optical fiber array adjacent to optical grating couplers, and actively aligning the optical fiber array relative to the optical grating couplers in a yaw direction and a roll direction to determine a yaw and roll alignment at a first operating wavelength. The method may include actively aligning the optical fiber array relative to optical grating couplers in an x direction and a y direction to determine a first x and y alignment at the first operating wavelength, determining a second operating wavelength, and actively aligning the optical fiber array again relative to the optical grating couplers in the x direction and y direction to determine a second x and y alignment at the second operating wavelength.
