FIG. 1.

Temperature dependent ORP (left) and (Δns) 2 (right) of HTG-23.

FIG. 2.

Bragg reflection wavelength vs. optical rotatory power: red open circles are the measured ORP at λ = 633 nm, green filled circles at λ = 514 nm, and blue triangles at λ = 457 nm. Lines are fitting curves using Eq. (3) with only one parameter φo = 3.12 deg/μm.

FIG. 3.

Light leakage vs. analyzer rotation angle. Here, 0° means the analyzer is crossed with polarizer, and positive rotation angle represents rotation in right-hand direction. Red open circles are the measured light leakage at λ = 633 nm, green filled circles at λ = 514 nm, and blue triangles at λ = 457 nm. Dashed lines are the overall leakage of white light, including 30% red, 60% green, and 10% blue lights.
