Chiral mirror and optical resonator designs for circularly polarized light suppression of crosspolarized reflectances and transmittances

Hodgkinson Ian; Wu Qi; Arnold Matthew; Mccall Martin; Lakhtakia Akhlesh (Elsevier Science Bv, 2002)

A left-handed chiral sculptured thin film (STF) that reflects strongly at the wavelength of the circular Bragg resonance tends to partially convert the handedness of incident LCP (left-circularly-polarized) light to RCP ...
Structurallyperturbed chiral Bragg reflectors for elliptically polarized light

Hodgkinson Ian; Wu Qi; De Silva Lakshman; Arnold Matthew; Lakhtakia Akhlesh; Mccall Martin (Optical Society of America, 2005)

The structure of an inorganic chiral medium represented as a stack of identical form-birefringent layers that twist steadily with increasing thickness is perturbed by realigning a fraction of each layer to a fixed ...
Supermodes of chiral photonic filters with combined twist and layer defects

Hodgkinson Ian; Wu Qi; De Silva Lakshman; Arnold Matthew; Mccall Martin; Lakhtakia Akhlesh (American Physical Society, 2003)

We consider the circularly polarized localized modes of chiral photonic structures with combined central twist and isotropic layer defects. The general filter is shown to suffer from anomalous remittance and saturation ...
