Photolithography compatible large area metamaterial emitters with full polarization and beam control via continuous translation symmetry breaking

A photonic metamaterial emitter generates ≈300 μm optical beams at 460 nm with user defined polarization, intensity, and phase. By superimposing weak, continuously varying perturbations onto a translation symmetric slab metamaterial, an incident TE slab mode is converted into outputs with smooth intensity profiles spanning TE, TM, diagonal linear, and circular polarization states.
