Modulation-assisted tunneling in laser-fabricated photonic Wannier–Stark ladders
We observe Wannier–Stark (W–S) localization in curved photonic lattices, realized using arrays of evanescently coupled optical waveguides. By correctly tuning the strength of inter-site coupling in the lattice, we observe that W–S states become increasingly localized, and eventually fully localized...
