This work presents a short review of the current research on the acousto-optic mechanism
applied to optical fibers. The role of the piezoelectric element and the acousto-optic …

We present a scheme in which light is modulated through coherent perfect activity. By
irradiating two coherent beams from both sides to a magnetic material and controlling their …

A fast adjustable gain equalization filter for dense wavelength division multiplexing (DWDM)
system is reported. The method is based on a single long period fiber grating (LPG) which is …

We demonstrate acousto-optic modulation of a fiber Bragg grating in a birefringent
suspended core fiber up to frequencies of 5.2 MHz for the first time. At acoustic resonances …

A novel acoustic emission (AE) localization method and a detection system were proposed
to complete multi-source AE localization based on time reversal focusing imaging and fiber …

We demonstrate a new all-fiber electrically tunable modulation method which significantly
reduces the response time of a Bragg grating acousto-optic modulator. A 4 cm long device is …

A flexural wave is applied to an optical fiber during the process of Bragg grating inscription
using the direct writing method through a phase mask. Using this approach, we can dither …

Fourier mode coupling model was first applied to achieve the spectra property of a fiber
Bragg grating (FBG)-based longitudinal-acousto-optic modulator. Compared with traditional …

A new method for fine control of the group delay of a fiber Bragg grating (FBG) is presented.
It is based on an acoustic wave applied to the fiber. The standing acoustic wave imposes a …

The inscription of customized fiber Bragg structures under acoustic excitation is proposed
and demonstrated. By setting the proper acoustic excitation function, the desired spectrum of …
