In this paper, we demonstrate a novel all-fiber wavelength-tunable acoustooptic switch
utilizing intermodal coupling in a two-mode fiber (TMF). Its all-fiber configuration consisting …

We demonstrate a tunable polarization-dependent loss (PDL) element based on the
polarization-dependent coupling of the fundamental core mode to the cladding mode by the …

We propose and demonstrate a novel apodization technique for an elliptical-core two-mode
fiber acousto-optic filter by twisting the fiber and adjusting the acoustic polarization. The …

A tunable notch filter is acoustically modulated in the transmission spectrum of a double-
core optical fiber. Flexural acoustic waves dynamically change the coupling power and the …

The etching effect on the bandwidth of acoustooptic coupling between core and cladding
modes in a single-mode (SM) fiber was investigated experimentally and theoretically. It was …

We demonstrate a novel all-fiber acousto-optic tunable notch filter based on coupling to
cladding modes in a single-mode fiber. The device has the advantage of low loss (< 0.1 dB) …

The efficiency enhancement of an acoustooptic tunable filter on cladding etched single-
mode fiber (SMF) is investigated experimentally. When the fiber diameter is etched down to …

We demonstrate numerically that acoustooptic interaction between two co-propagating
modes in an optical fiber can be utilized to obtain optical delays. Both positive and negative …

We propose and experimentally demonstrate a high-resolution distributed measurement of
the Brillouin gain spectrum in a polarization-maintaining fiber (PMF) using Brillouin dynamic …
