Long-period fiber gratings (LPFGs) functioning as band-reject filters have played a pivotal
role in the realm of optical communication. Since their initial documentation in 1996, LPFGs …

We investigate mode coupling in few-mode fibers induced by homogeneously and
periodically applied mechanical stress. To view the power transfer between individual …

We report on sensing characteristics of a long period grating fabricated in polymer
microstructured fiber using transverse periodic loading combined with fiber heating. The …

The inscription of a long-period grating in a side-hole single-mode fiber for sensing
application is demonstrated. The grating is made by pressing a plate with a periodic groove …

We demonstrate that higher order rocking filters coupling energy between polarization
modes at several wavelengths can be fabricated in a birefringent photonic crystal fiber using …

The characteristics of a mechanically induced long-period fiber grating (MLPFG) made by
pressing a pair of grooved plates over single-mode fiber tapers are analyzed. Fiber tapers …

In this article, we present detailed results on the fabrication and characterization of
mechanically induced gratings produced by winding a string around a fiber/tube set. A …

In this paper, we propose and demonstrate a versatile and simple single-, dual-and three-
wavelength switchable ytterbium-doped fiber laser using the intracavity induced-loss …

We describe a tunable double-clad Yb-doped fiber laser based on a long period fiber
grating mechanically induced in a section of single mode holey fiber inserted into the laser …

We report long period grating (LPG) devices based on a hybrid architecture incorporating
photopatternable fluorinated poly (aryl ether ketone) and silica layers for applications in …
