Abstract
A fiber-coupled phased-array includes a first photonic integrated circuit (PIC) and a second PIC. The first PIC includes a first set of lenslets and waveguides. The second PIC includes a second set of lenslets and waveguides and is placed at a distance from the first PIC. The optical fibers couple the first PIC to the second PIC and form an interferometric imager that can sample spatial frequencies of a target. Optical delay errors induced by a relative placement of the first PIC and the second PIC are compensated for.
