Abstract
A photonic integrated circuit (PIC)-based imager blade includes a number of PIC imager units stacked on top of one another. Each PIC imager unit includes a PIC coupled, at a first end and a second end, to a first set of lenslets and a second set of lenslets, respectively. An electronic integrated circuit (EIC) is coupled to the PIC. Pairs of lenslets of the first and second set of lenslets are optically coupled to respective waveguides embedded in the PIC. The PIC imager units have different lengths, and longer PIC imager units include larger lenslets.
