Fiber-Optic Pressure Sensor Based on π-Phase- Shifted Fiber Bragg Grating on Side-Hole Fiber
We present a fiber-optic pressure sensor based on a π-phase-shifted fiber Bragg grating (πFBG) fabricated on a sidehole fiber. Due to the resonance effect of a πFBG, its reflection spectrum features two notches that are dramatically narrower than the linewidth of a regular FBG of similar length. The narrow spectral notches allow high-resolution measurement of their spectral separation, signific...
متن کاملPhase Stabilization Method Based on Optical Fiber Link
—In this paper, we propose and prove the scheme by stabilizing the fiber link time delay in the increase of the signal’s (RF) transmitted phase stability. Let radio frequency signals (RF) transmit between the intermediate node and a distal end to obtain the difference of time delay. The faster and smaller proportion of delay fluctuation are eliminated by the piezoelectric fiber stretchers (PZT...
متن کاملPhase Noise Compensation with Limited Reference Symbols
Phase noise (PN) can cause severe link performance degradation in orthogonal frequency division multiplexing (OFDM) systems. In this work, we propose an efficient PN mitigation algorithm where the PN statistics are used to obtain more accurate channel estimates. As opposed to prior PN mitigation schemes that assume perfect channel information and/or require abundant reference symbols, the propo...
متن کاملPhase-reading, all-fiber-optic gyroscope.
An open-loop, all-fiber-optic gyroscope with wide dynamic range and linear scale factor is described. This novel approach converts the Sagnac phase shift into a phase shift in a low-frequency electronic signal by using optical phase modulation followed by amplitude modulation verify the theoretical predictions.
متن کاملBirefringence modulation in fiber-optic phase modulators.
We report an unusually large birefringence modulation in fiber-optic phase modulators formed with cylindrical piezoelectric transducers when driven at a few hundred kilohertz. The magnitude of the birefringence modulation is a strong function of modulation frequency. A simple model is used to explain the phenomenon, and the theoretical predictions agree well with the experimental results.
