Arrays of plasmonic nanohelices that are among the most optically chiral films in the visible wavelength region are fabricated. Remarkably, excellent results are achieved using a simple, one step method with great scalability. This is done by combining room‐temperature glancing angle deposition with the co‐deposition of titanium and silver.
