We demonstrate the first out-of-plane 2D focusing grating coupler (FGC), designed for compact photonicspintronic
integration allowing full polarization control of the emitted light. The couplers are designed
for a standard 220 nm-SOI platform and fabricated with 193 nm UV lithography. These couplers can
find applicability as polarization (de)multiplexers, optical layer couplers or to realize optically enabled
spintronic memory based on helicity dependent all-optical switching (AOS)[1,2].
