摘要
Chiral sculptured thin films of zinc selenide with different helical periods were deposited on both sides of a glass slide using the serial bideposition technique in order to fabricate a dual-band circular-polarization filter polarizer that exhibits two distinct circular Bragg regimes for a wide range (about 45 degrees) of the angle of incidence. This device can be angle tuned within a +/- 8% spectral range.
