High birefringent rhombic-hole photonic crystal fibers

Investigation of high birefringence and chromatic dispersion management in photonic crystal fibre with square air holes

“…Furthermore, the chromatic dispersion can be easily adjusted by only manipulating the internal angle of the rhombic air holes. The birefringence was also studied for this structure [39]. Comparatively to elliptical hole PCFs, the authors have found that rhombic holes PCFs exhibit more birefringence, up to 3 10 …”

Multi-Beam Interference Advances and Applications: Nano-Electronics, Photonic Crystals, Metamaterials, Subwavelength Structures, Optical Trapping, and Biomedical Structures

“…In some cases, the motif geometry plays a significant role in the performance characteristics of a device fabricated using MBI. For example, the lattice point geometry has been shown to affect the photonic-bandgap characteristics in photonic crystals [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45], selective plasmonic excitation in plasmonic crystals [46], photonic crystal laser beam pattern [47] and polarization mode control [48], birefringence of photonic crystal fibers [49], cell behavior in tissue engineering [50], tuning of surface textures [51], magnetization switching in periodic magnetic arrays [52], and, negative refraction and superlensing in metamaterials [53,54]. Accordingly, several studies report analytical and computational methods to select individual beam parameters to change the motif orientation and shape [34,42,55,56] from hemispherical to hemielliptical [57]; circular to triangular [58]; as well as, general structures including micro-cavities, micro-bumps, and rectangular bumps [51].…”

Dispersion Properties of Photonic Crystal Fiber with Four cusped Hypocycloidal Air Holes in Cladding

“…The effective cladding index depends on the geometry of the PCF structure, such as the dimension, air hole shape and pitch. There are many researchers have been reported with different structures such as circular [5,9], elliptical air holes [13], rhombic holes, double air hole unit, four air hole unit so on [14][15][16]. These studies show that the required properties of the PCF can be achieved just by choosing the suitable air hole geometry and pitch.…”
