Omnidirectional photonic bandgap in one-dimensional photonic crystals containing hyperbolic metamaterials

Abstract

We theoretically and experimentally investigate the angle-dependent omnidirectional photonic bandgap (PBG) in one-dimensional photonic crystals (PCs) comprising hyperbolic metamaterials (HMMs) for TM polarization, which is different from blue-shifted PBG in conventional all-dielectric photonic crystals. The frequency range of PBG increases when the incident angles increase, owing to the red-shift and blue-shift of the long-wavelength and short-wavelength band edges, respectively. The red-shifted band edge originates from the phase-variation compensation mechanism between the HMMs and dielectric material. The experimental values are in good agreement with the simulation results. These nanostructures are ideal for fabricating photonic devices such as omnidirectional reflectors.

Photonic band gap analysis of 1D TiO2/SiO2 photonic crystals using plane wave method for thin film solar cell applications

“…The frequency range enhanced due to the incident angle materials and showed red-shifting. The experimental results were found in better agreement alongwith the simulated results and fabricated nanostructures were useful for photonic devices [10]. Saravanan and Dubey fabricated the TiO2/SiO2 multilayer structure using sol-gel spin-coater and suggested for TFSC applications.…”

Twisted Bands with Degenerate Points of Photonic Hypercrystals in Infrared Region

“…Figure 3c shows the magnetic field distributions of the three points in the band structure of Figure 3a. We can see that the magnetic field profiles in PCs with HMM rods are very unique by comparing them to those in PCs with conventional dielectric rods [19]. On one hand, Type-I HMMs have different longitudinal and transverse components of the effective permittivity; on the other hand, the absolute value of the longitudinal components of the effective permittivity of HMM was very large in the infrared region.…”

“…One example is a kind of novel optical material named photonic hypercrystals (PHCs) [16][17][18]. PHCs can have new properties, such as omnidirectional band gap [19] and Goos-Hanchen shift [20], which show increasing potential in achieving devices with good performance. On the other hand, in the PHC system, the properties of HMMs can also be modified by PCs [21], which could bring new phenomena.…”

“…Extant studies mostly focused on the type of transformation of HMMs [9,10], as well as continual discovery of novel properties of HMMs [16][17][18][19][20]. The property of two-dimensional (2D) PHCs has not yet been studied adequately.…”

Design and analysis of 1D photonic crystal doped with magnetized cold plasma defect for application of single/multi-channel tunable narrowband filter

“…Metal included PhCs are utilized to realize Tamm plasmon polariton effect for filtering and sensing applications [21,22]. Metamaterial-based PhCs have experienced a notable growth for their negative permittivity, unique EM properties, and potential applications in microwave frequency [23]. PhCs designed with superconducting materials offer small damping effect and reduce dielectric loss.…”
