We propose a new hollow ring core silica photonic crystal fiber that can support 101 orbital
angular momentum (OAM) modes, maintaining a high mode quality without phase distortion …

Two photonic crystal fiber structures with quad-core have been investigated in this paper.
Both the structures are geometrically similar but have different background materials. Both …

We proposed a novel photonic crystal fiber composed of a double-cladding square lattice
that could be used in dual-band, Er and Tm optical gain bands, simultaneously supporting a …

This article proposed an ultra-large negative dispersion defected octagonal PCF (OPCF) to
address the issue of dispersion in fiber communication. Using the Finite Element Method …

In this work, we report for the first time, a simplex index guiding circular PCF (CPCF)
structure operating from 1350 nm to 1650 nm wavelength, which exhibits a highly negative …

We proposed a new type of photonic crystal fiber (PCF) using two nano-scale elliptical air
holes in the core region to control the property of birefringence and reduce the performance …

This paper presents a highly nonlinear dispersion compensating square-lattice photonic
crystal fiber (S-PCF). To investigate the guiding properties of the proposed PCF, full vector …

A single-mode defected core hexagonal photonic crystal fiber (H-PCF) is presented for the
wide-band dispersion compensation at the wavelength interval 1350 to 1600 nm over the …

We propose a triangular-multicore hollow optical fiber (TMC-HOF) design for uncoupled
mode-division and space-division multiplexing. The TMC-HOF has three triangular cores …

Square photonic crystal fibre (PCF) is proposed in this study using the principle of the
golden ratio; by taking inspiration from nature. Simulations and analyses of the proposed …
