“…where, a co , ∆, V, and f(V) denote the fiber core radius, the normalized core-cladding index difference, the normalized frequency, and the beatlength dispersion, respectively [12]. The change of optical beatlength is caused by changes of the core radius and the refractive indices under a strain.…”

Abstract:We report the axial strain dependence of two types of all-fiber acousto-optic tunable filters based on flexural and torsional acoustic waves. Experimental observation of the resonant wavelength shift under applied axial strain could be explained by theoretical consideration of the combination of acoustic and optical effects. We discuss the possibility of suppressing the strain effect in the filters, or conversely, the possibility of using the strain dependence for wavelength tuning or strain sensors.

“…Similar to the conventional and elliptical core two-mode fibers, the two-mode PCFs discussed above can be used for a number of applications [18,[22][23][24][25][26][27][28][29][30][31] such as mode converters, mode selective couplers, bandpass/bandstop filters, acousto-optic frequency shifters, acoustic-optic tunable filters, wavelength tunable optical switches, add-drop multiplexers, nonlinear frequency conversion, dispersion compensator, variable optical attenuator, and interferometric fiber sensors. However, the wavelength range for two-mode operation in the PCFs is many times bigger than that of the conventional core elliptical fibers, allowing for two-mode devices with much broader wavelength range to be created.…”
