Abstract

Structurally chiral materials exhibit the circular Bragg phenomenon (CBP). These materials preferentially reflect circularly polarized light of the same handedness while transmitting circularly polarized light of the opposite handedness within a range of wavelengths called the circular Bragg regime. The CBP has been extensively investigated experimentally for normal incidence, but not for oblique incidence. After fabricating a 20-periodthick chiral sculptured thin film, we measured all of its circular remittances over a 60◦ range of the angle of incidence and a 300-nm range of the free-space wavelength. Provided the incidence is not very oblique, the obtained dependencies of the center wavelength and the bandwidth of the CBP on the angle of incidence match theoretical estimates.
