Polarization-coupling all-fiber acousto-optic tunable filter insensitive to fiber bend and physical contact

Opt Express. 2009 Apr 13;17(8):6096-100. doi: 10.1364/oe.17.006096.

Abstract

We show that an all-fiber acousto-optic tunable filter based on polarization mode coupling using torsional acoustic wave is immune to the fiber bend and physical contact in the acousto-optic interaction region. We also propose and demonstrate a novel strain-free and size-reduced tunable filter with a 4-m-long fiber acousto-optic interaction region looped into a 5- cm-diameter coil.
