In this work, we present the advantages of driving a multichannel acousto-optical deflector
(AOD) with a digitally synthesized multifrequency RF signal. We demonstrate a significant …

We investigate codirectional mode coupling induced by periodic microbending in
polarization-maintaining (PM) fibers by using both an acoustic flexural wave and a pair of …

We couple a variable-coherence light beam into a multimode optical fiber and observe the
fiber cross-sectional images. The variation in the fiber imaging is explored as we change the …

We demonstrate a broadband all-fiber-optical parametric amplifier for ultrafast time-stretch
imaging at 1.0 μm, featured by its compact design, alignment-free, high efficiency, and …

Dispersion compensation up to the third order is experimentally demonstrated by using a
dual-fibre stretcher combined with the coma of an imaging lens, in a fibre-based scan-free …

An acousto-optic tunable filter (AOTF) is used in the development of hyperspectral imagers
from the ultraviolet to the longwave infrared. The spectral response of the transmitted …

In this work, a technique to improve the dynamical behavior of a non holographic fiber
specklegram sensor for measuring high frequency mechanical perturbations is …

An opto-electronic radio-frequency oscillator that is based on forward scattering by the
guided acoustic modes of a standard single-mode optical fiber is proposed and …

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 …

The effect of axial variations in acoustooptic phase-mismatch coefficient of a two-mode
birefringent photonic crystal fiber (PCF) is studied experimentally using two different …
