Optical properties of isotropic chiral media
WebThe chiral specificity also allows for symmetry-allowed SFG in isotropic chiral media, confirming predictions made approximately 50 years ago. With these experimental demonstrations in hand, an important challenge is the construction of intuitive predictive models that allow the measured chiral response to be meaningfully related back to ... WebApr 7, 2024 · A chiral dopant ((R)-BB, 0.05 or 0.25 wt%) was also added, in order to induce with a pitch of 44.7 or 8.9 µm. Once introduced into a 20 µm thick electro-optical cell, the chiral nematic helices experience a confinement ratio of ≈0.5 and ≈2.2, which leads to the formation of HH and SFLH patterns, respectively, once low voltage is applied.
