Fiber coupler based on dual-core fiber long-period grating
In this work, we proposed a dual-core fiber coupler. Identical long-period fiber grating is written in each core of the dual-core fiber by using point-by-point high-frequency CO 2 laser irradiation.
Fabrication and Mode Coupling of Long-Period Fiber Grating
A long-period fiber grating (LPFG) couple light from the fundamental guided core mode to co-propagating cladding modes at specific resonance wavelengths. A LPFG can be fabricated by
Dual-Pitch staggered Long-Period fiber grating for mode conversion
In this study, we propose and demonstrate a dual-pitch staggered long-period fiber grating (DSP-LPFG) that enables mode conversion between two distinct mode pairs.
Long Period Fibre Gratings
The strain response of a long-period fibre grating arise due to the physical elongation of the fibre, changing the grating pitch and the effective refractive index of the core and cladding due to the
Advances on Mode-Coupling Theories, Fabrication Techniques, and
In this paper, we have briefly review the developing history and recent advances made with regard to helical long-period fiber gratings (HLPGs) in three aspects, i.e., the mode-coupling
Long-period fiber grating
A long-period fiber grating couples light from a guided mode into forward propagating cladding modes where it is lost due to absorption and scattering. The coupling from the guided mode to cladding
Efficient Fabrication of Compact Long-Period Gratings Using CO₂
Abstract: We propose to inscribe a compact and reproducible long-period fiber grating (LPFG) in a standard single-mode fiber by a CO2-laser splicer that allows twisting the fiber stepwise
Mechanically Induced Long-Period Fiber Gratings and Applications
This paper presents a review of the evolution of LPFGs, with a specific focus on the progression and current trends of mechanically induced long-period fiber gratings.
Cladding mode coupling in long-period gratings in index-guided
Abstract To inscribe the long-period gratings (LPGs) in an index-guiding (or the solid-core) microstructured optical fiber (MOF), the opto-geometrical parameters of the fiber have to be
