We have studied circular dichroism (CD) in the visible region of composite and double-layer films consisting of a transparent chiral molecule, glucose, and an absorptive achiral dye, rhodamine. Composite and double-layer films show an absorption-induced CD response caused by chirality of glucose at 540 nm, where the rhodamine exhibits absorption. More importantly, in double layers, the polarity of the ellipticity in CD signals is found to be reversed when the incident direction is reversed. We discuss the origin of the polarity reversal, which is very similar to the magneto-optical effect, at the chiral meta-interface without magnetic field.
