Abstract
We adopt genetic multi-objective optimization to design dielectric multilayers that support superchiral surface
waves across a wide range of wavelengths. Our research reveals that it is possible to obtain extremely simple
platforms that can significantly enhance the optical chirality in a wavelength range of hundreds of nanometers.
Additionally, we demonstrate that this approach enhances the circular dichroism signal by more than two orders
of magnitude when a layer of chiral molecules is deposited on top of the dielectric stack. As a result, our findings
potentially expand the capabilities of chiral spectroscopies beyond what is usually possible with conventional
circular dichroism measurements.
