Modal parameter analysis for crown glass and phosphate glass photonic crystal fiber

Multiple material domain‐based computational tools for ease assessment of modal parameter in photonic crystal fibers

“…This imparts an effective refractive index (n eff ) instead. To evaluate effective refractive index, one has to calculate the related parameter, that is, the filling factor f which is given as follows 8,9,25 :…”

“…In addition to the f, the effective refractive index depends upon the additional structural parameters such as d/Λ and λ/Λ. The effective refractive index is given by 9,25…”

“…Here, N s and n air are the refractive index of the glass materials and refractive index of air, respectively. To build up modal parameter study of PCF, we introduce one significant parameter, that is, V parameter, which decides whether the fiber is falling under single-mode or multi-mode fiber operation with a cut-off range of~2.405 [14][15][16][17][18][19][20][21][22][23]25 :…”

Predicting different losses of photonic crystal fibers in material and hetero-core domain

“…This validates our results towards different material domain. Moreover, in effective index method the parameter shows an enormous variation in the parameter with slight change in refractive index of the material used [8].…”

“…In this study, we concentrate on the macro-bending and splice losses encompassing all possible offsets. Towards these, we take into account crown and phosphate based PBG fibers [8]. Further, we also analyze the hetero-core spliced fiber inclusive of step-index single mode fiber and PBG structure in different material regime which can be endured in practical applications.…”
