We propose the generation of high-purity perfect cylindrical vector beams (PCVB) using the Fourier transformation of Bessel-Gauss vector beams. The demonstration of PCVBs is implemented via an interferometric method employing a spatial light modulato

Abstract In this work, we demonstrate the measurement of the Brillouin gain spectra of vector modes in a few-mode fiber for the first time using a simple heterodyne detection technique. A tunable long period fiber grating is used to selectively excit

In vitro replication of traumatic spinal cord injury is necessary to understand its biomechanics and to improve animal models. During a traumatic spinal cord injury, the spinal cord withstands an impaction at high velocity. In order to fully assess t

We propose and demonstrate the use of the cost-effective electric arc writing method for the all-fiber cylindrical vector beam (CVB) and orbital angular momentum (OAM) beam generation in few-mode fibers (FMFs) for the first time to the best of our kn

We demonstrate a new guiding regime termed endlessly mono-radial, in the proposed annular core photonic crystal fiber (AC-PCF), whereby only modes of the fundamental radial order are supported by the fiber at all input wavelengths. This attribute is

We report a long period fiber grating (LPFG) with smallest grating pitch fabricated using electric arc-induced approach. The LPFG written in the few-mode fiber can achieve efficient and stable propagation of cylindrical vector beams supported by the
