Thus, combining the two phase-shifting degrees of freedom, the LHCP and RHCP wavefronts can be independently controlled while the polarization is not flipped after transmitting through the MS.

Abstract:

Taking advantage of multimaterial additive manufacturing, this work demonstrates a kind of polarization-maintaining metasurface (MS) for spin-decoupled beam shaping. The wavefronts of the two spin states, i.e., the left-hand circular polarization (LHCP) and the right-hand circular polarization (RHCP), can be independently manipulated while the output spin state remains the same as the input. The meta-atom is implemented with dual-polarized antennas at the top and the bottom with phase delay lines connecting them. The dual-polarized antenna on the receiving side is fixed to receive the LHCP/RHCP incident waves, while the dual-polarized transmitting antenna is rotated, providing the opposite phase shifts for the LHCP and RHCP. The absolute value of the phase shift is the same as the transmitting antenna's rotation angle. Meanwhile, varying the length of phase delay lines introduces 2π phase shifts for both LHCP and RHCP inputs. Thus, combining the two phase-shifting degrees of freedom, the LHCP and RHCP wavefronts can be independently controlled while the polarization is not flipped after transmitting through the MS. One MS produces vortex beams with different topological charges for LHCP and RHCP. The other achieves spin-decoupled focusing. The multilayered MSs are conveniently printed using multimaterial additive manufacturing without postprocessing.
