Dual polarization fiber grating laser hydrophone.
A novel fiber optic hydrophone based on the integration of a dual polarization fiber grating laser and an elastic diaphragm is proposed and experimentally demonstrated. The diaphragm transforms the acoustic pressure into transversal force acting on the laser cavity which changes the fiber birefringence and therefore the beat frequency between the two polarization lines. The proposed hydrophone ...
متن کاملPolarization-maintaining fiber-optic-grating vector vibroscope.
A fiber-optic vector vibroscope based on orthogonal polarization cladding-to-core recoupling is demonstrated. A compact structure in which a short section of polarization-maintained (PM) fiber stub containing a straight fiber Bragg grating (FBG) is spliced to another single-mode fiber. Two well-defined orthogonally polarized cladding modes reflected by the PM-FBG are recoupled at the junction a...
متن کاملSwitchable UWB pulse generation using a polarization maintaining fiber Bragg grating as frequency discriminator.
We propose and successfully demonstrate a novel approach to optically generate ultrawideband (UWB) pulse with switchable shape and polarity by using a polarization-maintaining fiber Bragg grating (PM-FBG) as frequency discriminator. Depending on the shape of the reflective spectrum of the PM-FBG, the system can function as a first- or second-order differentiator for the generation of Gaussian U...
متن کاملTemperature-Independent Fiber Inclinometer Based on Orthogonally Polarized Modes Coupling Using a Polarization-Maintaining Fiber Bragg Grating
A reflection fiber inclinometer is proposed and experimentally demonstrated based on two linearly polarized (LP) modes coupling. The configuration consists of a section of polarization-maintaining fiber (PMF) containing a fiber Bragg grating (FBG) splicing with single mode fiber (SMF). Bending the PMF in the upstream of FBG can induce an additional birefringence of PMF, which results in the int...
متن کاملFiber optic Sagnac loop with a polarization maintaining photonic crystal fiber as an optical wavelength demodulator for fiber Bragg grating sensors
The properties of a fiber optic Sagnac loop with a polarization maintaining photonic crystal fiber are presented, which is utilized as an optical wavelength demodulator. Owing to the use of a photonic crystal fiber, which has high birefringence and a very low temperature coefficient of birefringence, a temperature-stable optical wavelength demodulator circuit was obtained. The constructed demod...
