“…Guided modes in photonic crystal waveguides (PCWGs) have been extensively studied and experimentally realized for applications in magnetic mode control, nonlinear optics, high quality resonators, on-chip photonic lasers, and LSCs. − PCWGs are capable of guiding emitted light into waveguide modes, thus, increasing the optical efficiency of waveguides for LSCs. For the purposes of light trapping in LSCs, we consider the 2-D PCWG that is periodic in the x and y plane with a defined thickness, t , in the z plane.…”

Photonic Crystal Waveguides for >90% Light Trapping Efficiency in Luminescent Solar Concentrators

et al. 2020

Luminescent solar concentrators are currently limited in their potential concentration factor and solar conversion efficiency by the inherent escape cone losses present in conventional planar dielectric waveguides. We demonstrate that photonic crystal slab waveguides tailored for luminescent solar concentrator applications can exhibit >90% light trapping efficiency. This is achieved by use of quantum dot luminophores embedded within the waveguide that absorb light at photon energies corresponding to photonic crystal leaky modes that couple to incoming sunlight. The luminophores then emit at lower photon energies into photonic crystal bound modes that enable highly efficient light trapping in slab waveguides of wavelength-scale thickness. Photonic crystal waveguides thus nearly eliminate escape cone losses, and overcome the performance limitations of previously proposed wavelength-selective dielectric multilayer filters. We describe designs for hole-array and rod-array photonic crystals comprised of hydrogenated amorphous silicon carbide using CdSe/CdS quantum dots. Our analysis suggests that photonic crystal waveguide luminescent solar concentrators using these materials these can achieve light trapping efficiency above 92% and a concentration factor as high as 100.

“…Under the magneto‐optical effect, the 1‐D magnetized ferrite spherical photonic crystals (MFSPCs) possess good magnetic tunability and excellent anisotropy, which have a promising future in the fabrication of multifunctional magnetically tunable absorbers, [ 25 ] optical circulators, [ 26 ] and filters. [ 27 ] Mehdian et al investigated the magneto‐optical properties and Faraday rotation effect of plasma‐ferrite composite magneto‐metamaterials and analyzed the variation pattern of the effective negative refractive index poles. [ 28 ] The magnitude of the negative effective refractive index pole varies with frequency, external magnetic field, and electron density of the plasma layer.…”

Based on a spherical coordinate system and Maxwell's set of equations, the calculation formulas of one‐dimensional (1‐D) magnetized ferrite spherical photonic crystals (MFSPCs) are obtained and treated with the solution method of the spherical Bessel equations. Combined with the conventional transmission matrix method, expressions for the absorptance, reflectance, and transmittance of the 1‐D MFSPCs are given. 1‐D MFSPCs consisting of the general dielectric and Yttrium iron garnet (YIG) are also designed to verify the correctness of the conclusions. Variables such as external magnetic field, incidence angle, initial radius, and YIG thickness effects on the features of such 1‐D MFSPCs are also discussed. The transformation of the external magnetic field has a linear relationship with the position of the absorption band (AB). The three variables of incidence angle, initial radius, and YIG thickness have a substantial influence on the width and position of the AB, which can be adjusted according to the actual demand and are of high application significance. The results of this study can be helpful for the design of multifunctional absorbers and radome.

The dispersion characteristics and phase index of electromagnetic waves in two types of magnetized one dimensional ferrite photonic crystals with mixed field configuration are studied for transverse magnetic mode. The dispersion equation and formula for phase index are derived using transfer matrix method. It is found that in type-1 & type-2 magnetized one dimensional ferrite photonic crystals, photonic band gaps (PBGs) show dependence on HOYIG and HONI respectively. The PBGs corresponding to thinner YIG layer are at higher frequency side at fixed. The variation of frequency-filling factor shows that PBGs occur in the form of lobe for both types. It is observed that the phase index is strongly influenced by external magnetic fields, and filling factor. It is demonstrated that PBGs in phase index occur in the form of lobes at fixed. Also, with decrease in the magnitude of phase index, number of lobe increases. The phase index, field and frequency plots show that there are multiple peaks in the PBGs of phase index in the lower frequency.
