Geometric-phase signature of a structurally chiral dielectric slab with
a central phase defect
A slab made of a dielectric structurally chiral medium (DSCM) strongly reflects the co-handed circularly polarized plane wave, but not the cross-handed circularly polarized plane wave, in a spectral regime called the circular Bragg regime. The effect of inserting a central phase defect in a DSCM slab with a modest …
