We propose a dynamic scheme to realize mode-switchable generation of LP_11a/b modes
and±1-order orbital angular momentum (OAM) modes simultaneously, which are induced by …

Temporal and spatial resonant modes are always possessed in physical systems with
energy oscillation. In ultrafast fiber lasers, enormous progress has been made toward …

We propose a novel model of the acousto-optic interaction in circular fibers endowed with
the lowest-order flexural acoustic wave that is based on the actual distribution of the …

We demonstrate an acoustically induced fiber grating (AIFG) modulated by acoustic flexural
wave propagating along polarization-maintaining fiber (PMF). At the wavelength of …

Long period gratings in low-index contrast solid-core photonic bandgap fibers are a
promising platform for fiber-based fluid refractive index sensing with very low detection …

We demonstrate a coherent intermodal coupling in a hollow-core photonic bandgap fibers
(PBGF) using an acoustic grating. A theoretical study on the properties of acoustic and …

We present a method to calculate the acousto-optic coupling coefficients between the
guided modes of optical fibers in a standing acoustic wave. We show that our results are in …

A single-mode fiber (SMF) acousto-optic tunable filter (AOTF) with a tuning range of more
than 300? nm is demonstrated. The SMF used in the experiment has a ring of symmetric …

Here we theoretically and experimentally demonstrate a way to control the intensity of
optical vortices by a magnetic field directed along the beam axis. We describe the principle …

Bu doktora tez çalışması iki temel konu üzerine yoğunlaşmıştır; ilk olarak, sol-jel daldırma
yöntemi kullanılarak nano tanecikli titanyum dioksit (TiO2) ince filmi farklı tavlama …
