Strongly Deflecting Cylindrical Metalenses for Ultra-Compact Spectroscopy
Paper i proceeding, 2022
We demonstrate all-dielectric, strongly deflecting cylindrical metalenses for near-infrared spectroscopy applications. We followed two design workflows: phase mapping using finite element method-simulated metaatoms and the diffracted energy redistribution approach. Optimized metasurfaces were fabricated directly in GaAs substrates. These high-NA planar optical components will be useful for monolithic integration with compact semiconductor light sources for beam shaping and spectroscopy.
