Linear-fan configuration of photonic integrated circuit imagers

Abstract:

A photonic integrated circuit (PIC) imager includes a substrate, and a number of PIC imager units disposed in an arbitrary configuration on the substrate. Each PIC imager unit includes a PIC coupled to an optical connector, and a number of lenslets configured as a linear lenslet array and optically coupled to an edge of the PIC. Pairs of lenslets of the linear lenslet array are optically coupled to respective waveguides embedded in the PIC.
