1. A method comprising:
illuminating a photonic integrated circuit (PIC) of a transmit aperture of a laser communication terminal and a PIC of a receive aperture of the laser communication terminal with multi-wavelength light, each PIC comprising multiple antenna elements forming an optical phased array (OPA);
determining light intensities of different wavelengths of the multi-wavelength light after the multi-wavelength light has passed through each PIC starting from the multiple antenna elements;
estimating phases of light associated with the antenna elements based on variations in the light intensities; and
adjusting one or more phase shifters of at least one of the PICs based on the estimated phases of light.
