Abstract
The band gaps of photonic crystals (PCs) play an important role in light manipulation for many applications, such as reflectors, filters, and lasers. In traditional, one-dimensional all-dielectric PCs, as the angle of incidence increases, the gaps are blueshifted in wavelength for both transverse-electric (TE) and transverse-magnetic (TM) polarizations. However, this work predicts and demonstrates that redshifted gaps can be realized in one-dimensional PCs composed of alternating hyperbolic metamaterials and dielectrics for TM polarization, while for TE polarization the gaps remain blueshifted. This property facilitates the design of polarization selectors working in a wide angle range.
