The diversity of spatial modes present within a multimode fiber has been exploited for a wide
variety of imaging and sensing applications. Here, we show that this diversity of modes can …

The physical parameters affecting the bandwidth of acoustooptic tunable filter on single-
mode (SM) fiber are investigated. Compared to standard step-index SM fiber, we found that …

It is shown that the controlled multi-tapering of singlemode optical fibres can be considered
as another degree of freedom in tailoring the spectral characteristics of dynamic acousto …

We demonstrate coherent transfer of an ultra-stable optical frequency at 192.8 THz over 50-
km spooled fiber. Random phase noise induced by environmental disturbance through fiber …

We demonstrate a novel electro-optic swept source for wavenumber-linear interferometric
sensing and imaging applications. The electro-optic swept source based on an acousto …

High‐quality signal transmission and imaging through a multimode fiber is essential for
optical communications and medical endoscopic imaging, as it can provide high fidelity of …

A fiber-optic frequency shifter that couples light between two spatial modes is discussed.
The acoustic flexural wave that provides the coupling is excited in the fiber by pressing it …

For speckle pattern-based wavemeters or spectrometers, the intermodal and the chromatic
dispersion of the diffusion waveguide are key factors in determining the wavelength …

We demonstrate a novel kind of tunable optical delays based on dynamic grating generated
by Brillouin scattering in an optical fiber. An axial strain gradient is applied to a 15 m section …

The status of acousto-optic coupling in optical fibers as used for manipulation of the optical
power is reviewed. Some resulting effects of this process are frequency shifting, filtering …
