We propose an in-line wavelength selective core switch for multicore fiber (MCF)
transmission systems, based on the acousto-optic effect. A theoretical model addressing the …

An all-fiber, narrowband, tunable polarization controller is proposed and demonstrated. The
device is based on coherent acousto-optic mode coupling induced by two orthogonal …

We demonstrate two all-fiber low-frequency shift schemes based on the acousto–optic
interaction in a few-mode fiber (FMF). Two acoustically induced fiber gratings (AIFGs) are …

We report on a time-resolved acousto-optic interaction technique for the detection of axial
nonuniformities in single-mode fibers. It is based on the propagation of short packets of …

The time-averaging effect on fringes produced from a specklegram under time-varying
speckle illumination, by which undesirable speckle noise is successfully reduced, is studied …

A vibration sensing technique using the speckle contrast ratio from a multimode fiber is
introduced. This sensing technique is based on time integration by a CCD camera, from …

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 …

An all-fiber acousto-optic modulator (AOM), which features a compact structure and a low-
driving voltage, is experimentally demonstrated for the active mode-locking of a fiber laser …

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 …
