Abstract
Photonic bandgaps (PBGs) in conventional one-dimensional (1-D) photonic crystals (PhCs)
composed of isotropic dielectrics are polarization-insensitive since
the optical length within a isotropic dielectric layer is
polarization-independent. Herein, we realize polarization-sensitive
PBGs in hybrid 1-D PhCs composed of all-dielectric elliptical
metamaterials (EMMs) and isotropic dielectrics. Based on the Bragg
scattering theory and iso-frequency curve analysis, an analytical
model is established to characterize the angle dependence of PBGs
under transverse magnetic and transverse electric polarizations. The
polarization-dependent property of PBGs can be flexibly controlled by
the filling ratio of one of the isotropic dielectrics within
all-dielectric EMMs. Assisted by the polarization-sensitive PBGs,
high-performance polarization selectivity can be achieved. Our work
offers a loss-free platform to achieve polarization-sensitive physical
phenomena and optical devices.
