Bending-induced birefringence in single-mode fibers.
In a bent optical fiber, lateral internal stress induces a birefringence, betab. At lambda = 0.633 microm in a silica fiber, betab = 7.7 X 10(7) r2 /R2 deg/m, where r is the fiber radius and R is theExpand

Origins and control of polarization effects in single-mode fibers (A)
The polarization state of light in single-mode fibers is very sensitive to any perturbation which is not symmetric about the fiber axis. While this is a source of noise, drift, or signal fading inExpand

Magneto‐optic current sensing with birefringent fibers
To measure currents on high‐voltage lines, the Faraday rotation is used in a single‐mode optical fiber encircling the conductor. Disturbing linear birefringence is suppressed by twisting the fiber.Expand

Electromagnetic acceleration of macroparticles to high velocities
An inductively driven rail‐gun macroparticle accelerator has been built in which velocities of 5.9 km/s have been obtained using an arc as the driving armature. Simple theory is shown to be adequateExpand

Polarization mode dispersion in single-mode fibers.
In real single-mode optical fibers, imperfections cause the two possible polarizations to propagate at different phase velocities. This birefringence leads to different group velocities. We haveExpand

High birefringence in tension-coiled single-mode fibers.
Coiling a single-mode fiber of radius r under tension onto a cylinder of radius R produces a linear birefringence of βtc ≃ 28 × 107∊2r/R deg/m in the fiber at λ = 0.63 μm, where ∊z is the relativeExpand

Scanning the wavelength in high-birefringence fibers inherently measures the group delay difference, and not the phase delay difference, between the two polarization modes. Dispersion of theExpand

Polarization holding in birefringent single-mode fibers.
Perturbations in highly birefringent single-mode fibers couple the two polarization modes and degrade the polarization-holding ability. With a broadband source we demonstrate wavelength averaging ofExpand

Acoustic sensing with a single coiled monomode fiber.
A single monomode fiber-optic acoustic sensor is proposed. The acoustic wave differentially changes the phase velocities of the polarization eigenmodes in a tension-coiled fiber, leading to aExpand
