In this manuscript, a squared hollow-core photonic crystal fiber-sensor is introduced, which
can be used for efficient amino acid investigations using THz waves. Amino acid …

The present study reports a design procedure and numerical investigation of a photonic
crystal fiber biosensor. The proposed sensor is consisting of irregular arranged rectangular …

In this article, a circular air hole organized in a square manner cladding with porous core
using elliptical holes index-guiding photonic crystal fiber (IG-PCF) has been proposed and …

This paper investigates the theoretical development and characterization of different
rectangular photonic crystal fiber (R-PCF) sensors for terahertz waveguide applications …

In laser science and industry, considerable effort is directed toward designing fibers for fiber
laser and fiber amplifier applications, each of which offers a particular advantage over the …

The first demonstration of a 40 μm core homogeneously ytterbium-doped fully aperiodic
large-pitch fiber laser, to the best of our knowledge, is reported here. In this concept, the …

We propose a model to calculate the thermally induced mode loss evolution in the coiled
ytterbium doped large mode area (LMA) fiber. The mode loss evolution in the coiled …

A resonant-ring-assisted large mode area segmented cladding fiber (RR-SCF) with a high-
index ring in the core is proposed. Numerical investigations of the effects of the high-index …

A new multiobjective optimization framework is presented for designing large mode area
photonic crystal fibers (LMA-PCFs) with effective single-mode operation in the bent state. For …

In this paper we report on the examination of the temperature influence of the effective
refractive index and on the dispersion characteristics in air-hole lattice photonic crystal …
